基于条分法的铰接式混凝土砌块护坡稳定性分析

摘要

In this paper, the stability of articulated concrete block protected slope is being analyzed by using slice method. Firstly, calculated the stability of slope soil (no block) by using slice method. Secondly, calculated the stability of slope by improving slice method (take block into consideration), it is proved that Bishop slice method is more suitable after comparisons and analysis of these two method. Based on Bishop Slice method, the slope stability and safety coefficient with different slope angles and concrete block weight were further calculated. Results showed that the different slope angle, and blocks were not sensitive to the stability of protected slope.%利用条分法对铰接式混凝土砌块护坡稳定性进行了分析,首先采用条分法计算了护坡土体(无砌块)的稳定性,然后对条分法加以改进(考虑砌块)计算了护坡整体的稳定性,通过两种方法的比较分析,表明毕肖普条分法更为适合.基于毕肖普条分法,进一步计算了不同坡角和不同砌块重量时护坡的稳定安全系数,结果表明不同坡角和砌块重量对护坡的稳定性有较小的影响.
