摘要
本文通过对九畹溪滑坡的现场实际踏勘,确定了滑坡的地形地貌特征,滑坡体、滑带物质特征及滑床岩土体特征。在现场试验和室内试验的基础上,对滑坡在不同工况下的稳定性进行计算并得出结论,其计算结果对该地区滑坡治理提供了参考和依据。选取特征剖面,采用Morgenstern-Prince法分别计算了不同工况下斜坡的稳定性,计算斜坡的法向力和剪切力,分析该滑坡的稳定性情况。
Through the investigation of jiuwanxi landslide,we can find out the landform feature of landslide,the material feature of slide body,sliding belt,and the rock and soil mass feature of sliding bed.On the basis of field test and laboratory test,the stability of landslide under different working conditions is calculated and a conclusion is drawn,which provides a reference and basis for landslide control in this area.The characteristic section was selected and the stability of the slope under different working conditions was calculated by morgenstern-prince method.The normal force and shear force of the slope were calculated and the stability of the slope was analyzed.
