摘要
针对采用极限平衡分析法计算边坡稳定时,由于没有考虑条块间力,不能满足所有静力条件,计算安全系数较之其他较严格的方法偏低的问题,提出了考虑高边坡开挖过程引起的地应力释放荷载的改进Sarma法稳定分析方法,利用改进的Sarma法对某水电站高边坡进行了稳定分析,为分析岩质高边坡在开挖过程中的稳定安全提供了较切合实际的理论依据。
According to the problem that the forces among blocks are ignored in Sweden arc method in the stability calculation using limit equilibrium analysis,which can not meet all the static conditions and obtain lower safety parameters compared with other relatively stricter methods,we put forward the improved Sarma Method considering in-situ stress release load caused by high slope excavation.And we analyzed the stability of high slope of a hydropower station using this method,which provided a more practical theoretical basis for analyzing stability of high rock slope in the excavation process.
