摘要
老林场安置点边坡位于处于重庆市巫山县,巫山县城内移民安置居民点的建设形成了一系列的高边坡,给城镇居民生命财产安全带来较大的威胁。针对老林场老林场安置点边坡进行稳定性分析计算,发现边坡稳定现状为:土质(填土)边坡在各个剖面上土体整体破坏模式--天然状态下处于稳定&基本稳定但安全储备不足。饱和状态下处于极限平衡状态&不稳定状态,易在降雨作用下的解体、崩塌,并形成整体滑移破坏。岩质边坡整体处于稳定状态。结合极限平衡法及工程类比等分析手段,确定滑坡稳定性计算的物理力学参数;提出以抗滑桩加桩间挡土板为主的治理措施,对类似工程具有一定的参考价值。
The old farm resettlement site side is located in Wushan county,Chongqi province.The construction of resettlement settlements in Wushan county has formed a series of high slopes which threaten the life and property safety of urban residents.Based on the stability analysis and calculation of the slope at the resettlement point of the old forest farm,it is found that the stability of the slope is as follows: the overall failure mode of the soil mass (filled soil) slope on each section -- the soil mass is stable & basically stable in the natural state,but the safety reserve is insufficient.Under the saturated state,it is in the limit equilibrium state & unstable state,which is easy to disintegrate and collapse under the action of rainfall,and form the overall slip failure.The rock slope is in a stable state as a whole.The physical and mechanical parameters of slide stability calculation are determined by means of limit equilibrium method and engineering analogy.This paper puts forward some control measures based on anti-slide pile and soil retaining plate between piles,which is of certain reference value to similar projects.
