摘要
在分析某公路裂隙岩质边坡渗流时,合理选取了渗流分析模型,并综合考虑比较了单孔压水试验和裂隙统计取得的渗透系数,获得了能较好反映原位地质环境的修正渗透张量。利用该方法所获取的渗透参数并采用连续介质模型对该边坡工程分析计算,取得了与实际吻合的结果,并指出了边坡稳定性分析时考虑渗流场影响的必要性。
The model for seepage analysis is reasonably selected when the seepage field of the slope with fractured rock mass on certain road i-; analyzed, and the coefficients of permeability obtained from the pump-in tests and the field surw.y of rock mass structural faces are compared synthetically. The modified permeability tensor that can reflect the intrinsic geological environment elements is proposed. Finally, the method is applied to the seepage analysis of the slope project successfully by using the equivalent continuum model, and the satisfied results are obtained. It is pointed that it is necessary to consider the seepage field during analyzing the stability of slope.
