摘要
以红土乡黄堰塘滑坡为研究对象,采用一种全新的本构模型分析其土体力学特性,同时计算滑坡在自然状态下和暴雨状态下的稳定性系数及最大位移,并分析该滑坡的稳定性。研究结果表明,黄堰塘滑坡目前处于基本稳定状态,但在连续强降雨下易引发山体滑坡。经综合分析后,给出抗滑桩+截排水沟+格构抗滑桩+截排水沟+桩间挡土墙+格构+钢管注浆工程+监测工程+箱涵工程的合理治理方案。
In the current slope stability analysis,the most commonly used method is the limit equilibrium slice method.A new constitutive model is adopted to analyze the soil mechanical properties of the Huangyantang landslide at Hongtu Town.Meanwhile,the stability coefficient and maximum displacement of the landslide under natural state and rainstorm state are calculated respectively,and the stability of the landslide is analyzed.The results show that the Huangyantang landslide is in a basic steady state at present,but it tends to cause landslides when there is continuous heavy rainfall.Based on a comprehensive analysis,a reasonable management plan is finally proposed.
