以鄂西地区柳家凹软土地基滑坡为例,先介绍了该软土滑坡的工程概况,并简要分析了其成因机制。在此基础上,利用极限平衡法对该软土滑坡在自然和饱和两种工况下的稳定性进行了定量计算和分析,并用FLAC-3D进行了稳定性数值模拟,将二者所得结果进行比较分析,从而对该软土滑坡的稳定性给予更科学的评价,同时也期望对软土滑坡变形破坏得出规律性的认识。根据以上分析结果,对柳家凹软土滑坡提出了采用旋喷注浆成桩加固滑坡滑动带土,在滑坡前缘修建抗滑桩和坡面截排水等综合治理措施。
Taking the landslide in the soft foundation of Liujiacun in western Hubei Province as an example, the general situation of the soft landslide is introduced firstly, and the genesis mechanism is briefly analyzed. On this basis, the stability of the landslide under natural and saturated conditions was quantitatively calculated and analyzed by the limit equilibrium method. The stability of the landslide was numerically simulated by using FLAC-3D. So as to give a more scientific evaluation of the stability of the soft soil landslide. At the same time, it is also expected to recognize the regularity of deformation and damage of soft landslides. Based on the above analysis results, the comprehensive control measures of landslides in Liujiajang are proposed, which are the consolidation of landslide zone with rotary jet grouting, the construction of anti-slide piles at the landslide and the slope drainage.
