Fu Ming Fu , Zhang Tian
Abstract:There are some advantages in strengthening slope with the anchor bar, such as low project cost, convenient for construction and so on. It not only meets the requirement of the reliability of the construction, but also is economic and reasonable for the construction.
Key words: anchor bar; slope; strengthening
1.Introduction
Anchor technique uses strata geotechnical’s shear strength around bolt to deliver structures pulling force or keep strata of the excavation own stability. Due to the use of the anchor rod, Anchor strata produce compressive zone and have reinforcement effect to strata, can enhance the strength of strata, improve mechanical properties of strata, make structure and stratum together formed a kind of work together complex. Anchor system can effectively sustain tension and shear, improve shear strength of the potential sliding surface, so it can effectively prevent slope to produce sliding damage.

浅谈锚杆技术在边坡工程中的应用 1.引言
锚杆技术是利用锚杆周围地层岩土的抗剪强度来传递结构物的拉力或保持地层开挖面的自身稳定。由于锚杆的使用,使锚固地层产生压应力区并对地层起到加筋作用,来增强地层的强度,改善地层的力学性能,使结构与地层一起形成一种共同工作的复合体。锚杆体系其能有效地承受拉力和剪力,能提高潜在滑移面上的抗剪强度,有效地阻止坡体产生滑动破坏。
2.工程概况 某边坡长约60m,最大坡高约23m,坡度达50°~75°,为岩质边坡。距坡底边缘约
1.5~4m 处有1栋5层框架结构建筑物, 人工挖孔灌注桩基础,建筑物以中风化千枚岩为持力层。因岩石风化强烈，呈碎块状，结构松散，多为泥质充填。上覆残坡积粉质粘土，局部夹有泥状，强度较低。边坡坡体多处位置曾发生崩塌，对建筑物存在威胁，所以需对边坡进行加固，采用的是块石混凝土挡墙+锚杆进行支护。
3.锚杆支护设计 3.1 锚杆的设计
（1）采用全长黏结式锚杆，黏结材料为普通水泥砂浆，砂浆强度等级为M30，锚杆长度L 为10米，防护边坡高度h 为9米。锚杆锚固段长度为5m 。
（2）锚杆的布置形式根据施工条件及工艺的需求采用梅花行布置，且为了使锚杆的锚固力均匀作用于岩体表面，应采用相邻两行的锚杆错开布置。
（3）锚杆数量按每延米h 21h +/3.24根计，锚杆长度为L ，共计252根。
钻孔直径为φ90，钻孔数按(L-0.1)m/孔计， M30注浆数量平均按0.052m 3/孔计。
（4）锚杆的上、下排垂直间距取2.55m ，水平间距2.55m 。锚杆倾角：与水平线成20°角度向下成孔。
（5）锚杆杆体选用直径为28mm 的HRB400级钢筋。
3.2 锚杆计算
（1）侧向岩土压力的计算[1][2]
当支护结构向离开岩土体方向偏移至岩土体达到极限平衡状态时，作用在支护结构上的岩土压力称为主动岩土压力。其计算方法如下：
对于无外倾结构面的边坡，一般发生由岩体强度控制的破坏，计算公式按主
动土压力计算，但粘聚力C 取零，内摩擦角?用e ?（岩体等效内摩擦角）代替，
按表取值；破裂角按45°+?/2（?为岩体内摩擦角，由岩块内摩擦角标准值折减确定，折减系数按表取值）确定。
根据地勘报告可知，边坡岩体类型为Ⅳ类，取等效内摩擦角
e ?
为40，计算可得主动岩石压力
通过计算可得a E =175.77 kN/m 。
（2）锚杆轴向拉力设计值的计算 a Q ak N N γ= （3-2）
其中：a N 为锚杆轴向拉力设计值；ak N 为锚杆轴向拉力标准值；Q γ为荷载分项
系数，取1.3；tk H 为锚杆所受水平拉力标准值；α为锚杆倾角。
通过计算可得ak N =112.3kN a N =145.99kN
（3）锚杆钢筋截面面积的计算
其中：S A 为锚杆钢筋截面面积；ογ为边坡工程重要性系数（本工程边坡工程安
全等级为一级，取1.1）；2ξ为锚筋抗拉工作条件系数（永久性锚杆取0.69，临
时性锚杆取0.92）；y f 为锚筋抗拉强度设计值（标准值k y f =400a MP ，设计值
y f =360a MP ）。
根据计算可得S A ≥0.588 3210m -?，选用1φ28mm 的三级钢，
S A =0.6153210m -?。
（4）锚杆锚固体与岩土体锚固长度的计算
锚杆锚固段长度除应同时满足地层对砂浆的粘结力和砂浆对钢筋的握裹力要求外，还应满足构造设计规定的最少锚杆锚固长度的要求。

由公式计算可知a l ≥2.1m ，实际取a l =5.0m 。
3.3 锚杆施工工艺与要点
锚杆施工的工艺流程为：搭设脚手架——坡面开挖整修——测量定位——钻孔——清孔——锚杆安放——注浆——锚杆端部绑扎——冲洗坡面——浇框格——喷草籽
（1）本边坡为石质边坡，坡面开挖10cm 至框格底面后设锚杆、浇框格，再在框格内客土20cm 后喷播草、灌籽。
（2）施工时应注重边坡清理，锚杆孔清孔后方可放置锚杆并加压(0.4MPa)注浆，在孔内砂浆充分凝固后扎筋，现浇钢筋砼框格，锚杆端部弯折并与纵横骨架筋间逐点绑扎。
（3）钻孔前需测量定位，做好标记，孔距偏差小于150mm ，孔深误差小于50mm 。钻孔时尽量不扰动周围岩层，安放锚杆前注意将孔内积水和岩粉等吹洗干净且杆体应除锈。注浆时注意注浆压力及砂浆配比。
图3.7锚杆现场施工图
4.结论
边坡工程采用锚杆进行边坡加固,工程造价较低,对施工器械要求不高,在达到安全可靠的同时兼顾了工程施工的经济性和合理性。
(1)当今锚杆技术在工程中被广泛应用。将锚杆和混凝土护坡相结合,约束滑动土体。是一种有效的加固措施。
(2)在利用灌浆锚杆加固边坡前,一定要做好边坡的地质勘探工作。摸清各岩层的性质和水文地质情况。
(3)由于工程地质条件、灌浆压力、施工技术等因素影响,加固施工质量应给与足够的重视。

These three principle has always been regarded as a plumb-line for measuring the professional level of translation and a goal for translators to strive after. However, in the application of this principle, people come to find some unsatisfactory aspects of the three-character guide and have put foreword a variety of new standards or criteria of translation. Despite a variety of opinions, two criteria are almost unanimously accepted by all, namely, the criterion of faithfulness/accuracy (忠实/准确) and that of smoothness (流畅). We may also take these two criteria as the principle scientific literature translation. By faithful/accuracy, we mean to be faithful not only to the original contents, to the original meaning and views, but also to the original form and style. By smoothness, we mean not only easy and readable rendering, but also idiomatic expression in the target language, free form stiff formula and mechanical copying form dictionaries.

Professional literatures have been regarded as “intangible assets” of the whole world because they are, on the one hand, the summary, generalization, and development of the achievements obtained on the basis of previous experiences or studies; and on the other hand, they have been accumulated and handed down from generation to generation. In this sense, therefore, all kinds of literature are records of precious research findings and academic achievements, and the crystallization of human civilization. 作为一种重要的知识储备手段，各类文献已成为宝贵的资源宝藏，大大促进了 人类社会的进步。 专业文献一向被认为是全世界的“无形财产”。因为一方面它们是对前人的经验 或研究成果的总结，概括和发现；另一方面，又是人类长期积累、世代相传的

Dashboard From Wikipedia, the free encyclopedia This article is about a control panel placed in the front of the car. For other uses, see Dashboard (disambiguation). The dashboard of a Bentley Continental GTC car A dashboard (also called dash, instrument panel (IP), or fascia) is a control panel located directly ahead of a vehicle's driver, displaying instrumentation and controls for the vehicle's operation. Contents 1.Etymology 2.Dashboard features 3.Padding and safety 4.Fashion in instrumentation 5.See also 6.References Etymology Horse-drawn carriage dashboard Originally, the word dashboard applied to a barrier of wood or leather fixed at the front of a horse-drawn carriage or sleigh to protect the driver from mud or other debris "dashed up" (thrown up) by the horses' hooves.[1] Commonly these boards did not perform any additional function other than providing a convenient handhold for ascending into the driver's seat, or a small clip with which to secure the reins when not in use. When the first "horseless carriages" were constructed in the late 19th century, with engines mounted beneath the driver such as the Daimler Stahlradwagen, the simple dashboard was retained to protect occupants from debris thrown up by the cars' front wheels. However, as car design evolved to position the motor in front of the driver, the dashboard became a panel that protected vehicle occupants from the heat and oil of the engine. With gradually increasing mechanical complexity, this panel formed a convenient location for the placement of gauges and minor controls, and from this evolved the modern instrument panel,

Project Budget Monitor and Control Author：Yin Guo-li Nationality：American Derivation：Management Science and Engineering.Montreal: Mar 20, 2010 . With the marketing competitiveness growing, it is more and more critical in budget control of each project. This paper discusses that in the construction phase, how can a project manager be successful in budget control. There are many methods discussed in this paper, it reveals that to be successful, the project manager must concern all this methods. 1. INTRODUCTION The survey shows that most projects encounter cost over-runs (Williams Ackermann, Eden, 2002,pl92). According to Wright (1997)'s research, a good rule of thumb is to add a minimum of 50% to the first estimate of the budget (Gardiner and Stewart, 1998, p251). It indicates that project is very complex and full of challenge. Many unexpected issues will lead the project cost over-runs. Therefore, many technologies and methods are developed for successful monitoring and control to lead the project to success. In this article, we will discuss in the construction phase, how can a project manager to be successful budget control. 2. THE CONCEPT AND THE PURPOSE OF PROJECT CONTROL AND MONITOR Erel and Raz (2000) state that the project control cycle consists of measuring the status of the project, comparing to the plan, analysis of the deviations, and implementing any appropriate corrective actions. When a project reach the construction phase, monitor and control is critical to deliver the project success. Project monitoring exists to establish the need to take corrective action, whilst there is still time to take action. Through monitoring the activities, the project team can analyze the deviations and decide what to do and actually do it. The purpose of monitor and control is to support the implementation of corrective actions, ensure projects stay on target or get project back on target once it has gone off target。
