摘要
从地质条件出发,详细分析了滑坡的成因,以大型的岩土工程数值分析软件(ADINA)为研究手段,建立有限元计算模型,用强度折减的方法分析了滑坡体在初始工况、蓄水工况、暴雨工况、水位骤降工况和地震工况下的稳定情况,根据滑坡的失稳情况,在综合考虑的基础上,提出了削坡减载和地表排水相结合的治理措施,计算结果表明,治理措施是可行的,研究结果对设计和施工具有较大的参考价值.
In light of the geological condition of the landslide, the mechanism of the landslide is analyzed in detail. Taking the numerical analysis software ADINA for large-sized geoteehnical engineering as research method, a FEM model is established. By using the strength reduction method, the stable situations of the landslide under the primary situation, impounding situation, rainstorm situation, rapid drawdown situation, earthquake situation are analyzed in detail. According to the failure situation of the landslide, the treatment measures of cutting Mope and reducing load combined with surface drainage are presented comprehensively. The calculation results show that the treatment measures are advisable; the relevant conclusions and methods of our research take a good effect in design and construction.
