【摘要】：以某高岩质边坡为研究对象,详细介绍了该滑坡的治理与监测措施。首先详细地介绍了该滑坡的工程地质条件,该滑坡基岩为泥岩,在人为因素以及降雨等因素影响下,很容易造成其稳定性降低;其次选取了典型剖面,对其进行天然和暴雨工况下边坡稳定性计算,并以安全系数1.3进行剩余下滑力推算,完成其稳定性评价;在此基础上,经过设计比选后选取"预应力锚索+锚筋桩+钢筋混凝土挡墙"的治理措施,详细给出了设计结果及施工要点;给出滑坡治理工程的监测方案,以保证边坡的安全施工。本文提出的高岩质边坡治理与监测方案,可为类似高岩质边坡的处理提供一定的参考。
[Abstract]:Taking a high rock slope as the research object, this paper introduces the treatment and monitoring measures of the landslide in detail. Firstly, the engineering geological conditions of the landslide are introduced in detail, and the bedrock of the landslide is mudstone. Under the influence of human factors and rainfall, it is easy to reduce its stability. Secondly, the typical section is selected to calculate the slope stability under natural and rainstorm conditions, and the residual sliding force is calculated with the safety factor 1.3 to complete the stability evaluation. On this basis, the design results and construction points are given in detail by selecting the treatment measures of "reinforced concrete retaining wall with prestressed anchor cable anchor reinforcement pile" after the design comparison. In order to ensure the safe construction of the slope, the monitoring scheme of the landslide treatment project is presented. The treatment and monitoring scheme of the high rock slope presented in this paper can provide some reference for the treatment of similar high rock slope.
