【摘要】 结合麦秀山地区的工程地质特点,运用MIDAS,PHASE2有限元软件,分析了冬冻春融及路基填筑对高含水滑坡稳定性的影响。渗流规律的变化可能会对滑坡的稳定性造成影响;在路基填筑且春融坡面解冻前,整个坡体都是稳定的;路基填筑且春融坡面解冻后,高动水压力形成流土通道诱发滑坡进一步变形;填筑路基将导致坡体发生向下向前的位移。更多还原

【Abstract】 Combined with the engineering geological features of Maixiushan area in Qinghai Province, MIDAS and PHASE2 finite element software were used to analyze the influence of cycle of freezing in winter and thawing in spring and subgrade filling on the stability of landslide with high moisture. The change of seepage law may affect the stability of the landslide. Before the subgrade filling and slope is thawing on the spring, the entire slope is stable; after subgrade filling and slope is thawing on the spring, high dynamic water pressure leads to the formation of flowing soil channels, which induces further deformation of the landslide; Subgrade filling will cause the slope to move downward and forward.更多还原
