Based on the relationship between roughness and flow rate and the relationship between bed slope and water level.
在获得糙率流量关系和河床底坡水位关系基础上，计算出曼厅段在多种水位下的过水能力，最后获取三道拐不同水位的滞洪量。
Numerical simulating of rockfall in rock slope with block-like structure;
层状块体结构岩坡崩塌过程的数值模拟
The factor of safety of a rock slope thus calculated using these mechanicals parameters is not able to reflect the actual stability of the slope.
由于岩体强度试验得到的力学参数与实际情况偏差较大,利用试验所得岩体结构面强度参数计算得到的岩坡稳定性系数往往与实际情况有一定误差。
The example verified that these two methods have higher reliability and thus apply to assessing the stability of rock slope.
本文利用数值模拟结果得到的应力场，结合滑带分段，采用加权平均和力矩平衡两种方法估算岩坡稳定系数。
