摘要:
在连续多日的大暴雨后，某高边坡强卸荷松动的危岩体发生了大崩塌，根据测绘和三维激光扫描，崩塌陡崖基岩裸露，岩体为斜长花岗岩，陡崖高40~80 m，延伸长度近400 m。由于该段陡崖岩体曾多次发生过不同规模的岩体崩塌，在岩壁多处出现了"凹腔"，"凹腔"使上部的岩体形成了倒悬状，倒悬状岩体极易顺外倾结构面和张裂隙在内、外营力作用下发生掉块和崩落。文章以这一工点为研究背景，进行了陡崖边坡稳定性分析及评价，并针对不同稳定性特征的陡崖提出了不同的治理方案，可为类似工程提供借鉴。
Abstract:
After several days of torrential rain, the dangerous rock mass with strong unloading and loosening on a high slope collapsed. According to surveying and mapping and three-dimensional laser scanning, the bedrock of the collapsed steep cliff with a height of 40~80 m and an extension length of nearly 400m is bare and the rock mass is plagioclase granite. Because the steep cliff rock mass in this section has collapsed many times in different scales, the concave cavities where the upper rock mass form an inverted suspension appear in many places of the rock wall. The concave cavity made the upper rock mass form an inverted suspension. The inverted rock mass is easy to fall and collapse along the inclined structural plane and the tension crack under the action of internal and external forces. This paper, taking this construction site as the study background, carries out the stability analysis and evaluation of the steep cliff slope, and puts forward different treatment schemes for different stability characteristics of the cliff, which can provide reference for similar projects.
