摘要 长沙市某土质边坡经暴风雨后发生约60 m长的滑坡,经分析事故原因为抗滑抗剪能力不足、两次切坡造成阻滑区减小和地勘资料不准等。采用双排桩、重力式挡土墙方案进行综合治理后,历经5年,未出现明显变形、开裂等异常情况。

Abstract :
About 60 m soil slope slide happened in Changsha after a storm. After analysis, this accident was caused by deficient sliding resistance and shearing resistance, inaccurate geological survey and the resistance of the anti-slide segment being reduced after cutting the slope twice, etc. Double-row piles and gravity retaining wall were used for comprehensive treatment and they don't have abnormal conditions, such as obvious deformation and cracking, within 5 years.
Key words : soil slope slope slide treatment double-raw piles
