| 摘 要： | 四川某路堤初步验收后,在2013年7月暴雨期间发生了多处溜坍。在现场调查、试验的基础上,对溜坍原因进行综合分析,指出了溜坍原因是渗透破坏、高地下水压力、饱和软化和表面冲刷共同作用结果。针对性地采用了路基覆盖、砂袋堆砌和钢管桩临时加固措施及挡土墙、混凝土格构、分台阶分层回填、增设密目网等永久措施,经6个月运行检验,效果良好。

| Abstract: | There arose several collapses on an embankment in Sichuan after its initial acceptance during rainstorm period in July, 2013. Based on the on-site investigation and tests, it was found that, with the cause analysis, the collapse was resulted from infiltration damage, high pressure of groundwater, saturation softening and surface souring jointly. Therefore the temporary reinforcement measures, such as subgrade coverage, sandbag piled up and steel-pipe pile, and the permanent measures, such as retaining wall, concrete lattice, backfilling in benches and layers, addition of dense screen, were adopted and, by 6-month operation inspection, proved to have good effect. |
