Analysis of control and prevention technology system and engineering selection for unstable-rock

摘要:

危岩崩塌防治技术是保障危岩工程安全稳定的关键。通过对危岩崩塌防治技术的优缺点、适用条件、工程设置原则以及选型程序的分析，认为危岩崩塌防治技术可分为主动防治技术、被动防治技术和辅助防治技术，各项防治技术设计时应充分考虑其适用条件，按照工程设置原则采纳使用，适时选择多种技术组合方式的治理措施进行危岩崩塌工程防治；危岩崩塌防治技术选型应遵循查清危岩体基本情况→评价危岩体状态→选择危岩防治技术→分析防治技术选型结果的基本程序，确定危岩崩塌防治技术选型程序各环节的关键参数，以确定合适的崩塌防治技术。研究成果可为危岩崩塌防治工程设计提供理论依据和关键技术支撑。

Abstract:

The control and prevention technology for unstable-rock is the key to guarantee the safety and stability of unstable-rock. This paper analyzed the merit and demerit， application condition， engineering setting principle and selection program of the control and prevention technology， which is devided into three kinds， i.e.， active technology， passive technology and assisted technology. Application conditions of each technology should be considered when these technologies were designed. Each technology should be selected based on the engineering setting principle， and the treatment measure with multiple technologies to control and prevent unstable-rock should be duly selected. The selection of technology for unstable-rock engineering should follow such process of checking the basic information of unstable-rock → evaluating the state of unstable-rock → selecting technology → analyzing the result of selected technology， thus the key parameters of each part of this process were confirmed to select the suitable technology. This research achievement could provide the theoretical foundation and key technology support for unstable-rock engineering.
