岩质边坡稳定性的渗流耦合分析
COUPLING ANALYSIS ON THE STABILITY OF ROCKMASS SLOPE
【摘要】 分析总结了裂隙岩体水力行为特征以及对边坡稳定性的影响,指出了边坡稳定性分析时对地下水研究的重要性.通过对某边坡在天然状态下和在考虑渗流场作用时的三维有限元分析可知,渗流力的作用使边坡内破坏单元大量增加,安全系数也明显降低.
【Abstract】 In this paper the hydromechanical behaviors of fractured rock mass are analyzed and synthesized,and the lmportance of the seepage force of underground water is put forward. By the FEM calculation of a certain rockmass slope in a natural state and under the action of seepage force,the results show that the seepage force affects the stability of the rock slope greatly and the safety coefficient decreases largely and the results fit with the situ state very well.
