【摘要】：西南地区地质条件复杂,受地质灾害影响最为强烈,加上近年来极端气候现象与地震频发,地质灾害防治工作面临着更多复杂因素作用下的难题。以高烈度地区发育的巴郎村滑坡为例,在现场详细调查的基础上,对其破坏迹象与变形机理进行了深入分析,计算了不同工况条件下的稳定性系数。在此基础上,针对高烈度地区滑坡治理工程优化设计开展了进一步研究,利用数值模拟方法对两套治理方案进行了耦合分析与计算,从合位移与剪应力分布两个方面,对比分析了抗滑桩与挡土墙支挡效果,证实在高烈度地区抗滑桩工程具有更好的支护效果。该研究成果对高烈度地区滑坡灾害的防治工作具有一定指导意义。
[Abstract]:The geological conditions in Southwest China are complex, which are most strongly affected by geological disasters. In addition, in recent years, extreme climatic phenomena and frequent earthquakes have made the prevention and control of geological disasters difficult under the action of more complex factors. Taking Balangcun landslide developed in high intensity area as an example, on the basis of field detailed investigation, the failure signs and deformation mechanism of the landslide are analyzed in depth, and the stability coefficient under different working conditions is calculated. On this basis, the optimization design of landslide treatment project in high-intensity area is further studied, and the coupling analysis and calculation of two treatment schemes are carried out by using numerical simulation method, and the distribution of combined displacement and shear stress is analyzed and calculated. The effects of anti-slide pile and retaining wall are compared and analyzed, and it is proved that the anti-slide pile has better supporting effect in the area of high intensity. This research result has certain guiding significance to the prevention and cure work of landslide disaster in high intensity area.
