摘要
岩质高边坡,因其缺乏生物赖以生存的环境,即使经过传统的加固措施,却因暴露于地表,受到风吹、日晒、雨淋等各种破坏性侵蚀作用,表层岩石很容易降低强度,发生剥蚀脱落,降低边坡稳定性,危及工程的安全性。工程实践证明,影响边坡稳定性的因素很复杂,而且绝大部分因素是动态的、变化的,因此,滑坡灾害也是变化与发展的过程。针对岩质高边坡的特点,探讨了岩质高边坡的治理措施,介绍了一些新的边坡治理技术。
Even if traditional reinforcement has been made, rocky highwall slope still easy occurs insurfaee due to lack of survival environment for organism or bionts. By some destructive erosion, such as wind blowing, solarization and rain washing, strength of cap rock may be reduced, denudation and fall - off occurred and slope stability decreased, thus the safety of the whole works will be jeopardized. Engineering practices proved that reasons to endanger slope stability are complex, most factors are dynamic and always changeable. So, landslip disaster is only a part of changing and developing processes. Basing on the characteristics of rocky highwall slope, the author made studies on relevant control or disposal measures and recommended some new slope control skills and techniques.
