一种新的边坡稳定性评分体系

A new slope stability rating system

由于岩土工程的复杂性及其数据的不确定性、不完备性,需要发展经验评价边坡稳定性的体系,以适应中国山区交通工程建设的需要。基于Bieniawski的RMR体系、Barton的Q体系、Romana的SMR体系和Palmstrm的RMi体系发展出来一种边坡稳定性评分体系。新体系建立了新的不连续面状态描述和评分标准;考虑了天然降水的影响;对应控制性不连续面,考虑了其不连续面状态,并给出了评分方法。通过实例展示了新体系的易用性和一定的客观性。

It is necessary to develop empirical evaluation methods for highway construction in mountainous areas in China due to the complexity of geotechnical engineering and the lack of completeness and certainty of geotechnical engineering data.A new slope stability rating system based on Bieniawski’s RMR,Barton’s Q,Romana’s SMR and Palmstr?m’s RMi is put forward.The system employs a new method for describing and rating discontinuity condition considering the influence of raining.The condition of controlling discontinuity is considered in the system;and the rating standard for it is established.An example shows that the system is easy to use and objective to some extent.
