摘要
中缓倾角顺层边坡在张桑高速公路中分布较多,其稳定性影响因素及作用效果的分析对于边坡的稳定性判定及处治措施的制定有较好的指导作用。通过FLAC3D软件模拟计算并分析了边坡内不同水位高度变化下边坡稳定性的变化情况及水位高度与结构面倾角对于该类边坡稳定性的影响效果大小、何时占主导地位等问题,结果显示水位上升至边坡高度一半时,对稳定性影响明显,且该类边坡中,水位与结构面的相对位置也会对边坡稳定性产生影响。
The middle and slow dip bedding slope is more distributed in the Zhangsang expressway.The analysis of the influencing factors and the effect of its stability will play a guiding role in the determination of the stability of the slope and the establishment of the treatment measures.FLAC3D software is used to simulate and analyze the change of slope stability under different water height.Also it is used to analyze the effect of water height and structural plane inclination on the stability of this kind of slope and when to dominate.The results show that when the water level rises to half of the height of the slope,it has an obvious influence on the stability.In this kind of slope,the relative position of the water level and the structural plane will also affect the stability of the slope.
