| 摘 要： | 碎裂结构边坡稳定性受多组相交结构面控制，且受降雨、地震等多因素影响强烈，具有一定的特殊性。本文以某花岗岩碎裂结构边坡为例，在边坡的地质条件和岩体结构研究的基础上，结合施工及监测反馈信息，深入分析了边坡变形破坏模式，并根据稳定性计算结果，提出锚索、钢筋桩与排水相结合的支护方案。研究结果表明:坡体内部陡倾卸荷裂缝发育形成后缘切割面，中下部滑面追踪陡缓两组结构面发展；支护措施实施后，边坡经历512地震及雨季，多点位移计监测结果表明，地震和降雨对边坡稳定性影响较大，支护措施较好地控制了边坡变形。

| Abstract: | The stability of rock slope with cataclastic texture is controlled by joints that are crossed each other,and affected by terrain,rainfall and other factors.This paper presents a case study on the stability of a granitic rock slope with broken and cataclastic structures.The geological condition and the rockmass structure properties were investigated in detail.This study further took into account the data that are revealed during construction and monitoring of the slope.It thoroughly analyzed the slope deform... |
