摘要
农村水库库水涨落诱发的山体建筑滑坡危险性加大,而且会危机水库边缘居民安全。对此,提出农村水库库水涨落诱发山体建筑滑坡动力耦合预测方法。农村水库库水水位涨落变化容易造成山体建筑滑坡、引发库区发生危险,因此对水库边缘进行渗流场的分析,得出了水库边缘渗透场的有限元分析参数方程,设计了水库边缘水位动力增量载荷位移响应比预测模型,对水库边缘稳定性受库水水位涨落的影响进行动力耦合预测分析。实验证明,运用改进方法能够对农村水库边缘的稳定性进行有效预测与分析。
The mountain building landslide risk rural reservoir water fluctuation induced increase,and safety margin of residents crisis reservoir. In this regard,the rural reservoir water fluctuation induced landslide mountain building dynamic coupling prediction method. The rural reservoir water level fluctuation change is likely to cause the building mountain landslide,caused in danger,so the edge of the reservoir analysis the flow field,the reservoir edge penetration field finite element analysis of the parameter equation,the reservoir water level edge design incremental dynamic load displacement response prediction model,prediction and analysis of dynamic coupling is affected by water level fluctuation of reservoir edge stability. The experimental results show that using the improved. The method can effectively predict and analyze the stability of rural reservoir edge
