摘要
以简化Bishop法为基础,利用Matlab计算程序,求解红色粘性土的临界含水率,进一步求出临界损伤变量值。计算结果表明:临界损伤变量之大于1,不同于极限安全系数等于1,临界损伤值随击数的增加而变大,边坡稳定性可以用临界损伤变量来评价。
Based upon the simplified Bishop method, the critical moisture content of red sticky clay is achieved with Maflab computation program, then the critical damage variable. The computation results show that the critical damage variable is greater than 1, different from the limit salty variable which equals 1. The critical damage value increases following the increase of striking time. The stability of side slope can be assessed with the critical damage variable.
