某山区高填方路基边坡失稳机制分析研究
摘要:山区高填方路基边坡失稳往往是由于路基填料未进行有效处理、坡体内存在软弱面以及截排水措施不当等造成的。通过对某山区高填方路基边坡滑坡体形态和滑移特征、裂缝分布、周边地下水出露等方面综合分析,论述高填方路基滑坡机制,利用瑞典条分法及有限元数值模拟方法对边坡稳定性进行计算及评价,为滑坡治理方案提供参考。对此类滑坡的工程地质特征和重点关注问题进行了梳理与总结,可为今后类似情况提供借鉴。
Abstract:The instability and sliding of high fill subgrade slope in mountainous areas is often caused by the lack of effective treatment of subgrade filling, the existence of weak surface in the slope and the failure to take drainage measures in the surrounding areas. Based on the comprehensive analysis of the landslide shape and deformation characteristics, crack distribution, surrounding groundwater exposure and other aspects of a mountain high fill subgrade slope, the sliding mechanism of high fill subgrade landslide was discussed. The slope stability was calculated and evaluated by using Swedish slice method and finite element numerical simulation method, so as to provide reference for landslide treatment scheme. The engineering geological characteristics and key issues of this kind of landslide are sorted out and summarized, which can provide reference for similar situations.
