高速公路膨胀土滑坡稳定性分析及治理措施研究

STUDY ON STABILITY ANALYSIS AND CONTROL MEASURE OF SWELLING SOIL LANDSLIDE ON AN EXPRESSWAY

膨胀土滑坡威胁着工程建设施工安全,高速公路建设施工阶段受滑坡灾害的影响,易出现工体及填方滑塌、地表裂缝增大等安全生产隐患。以某高速公路膨胀土滑坡为例,对滑坡成因进行分析,并根据工程地质特征提出“抗滑桩+地表排水系统+坡内排水”的工程治理方案,降低了膨胀土质滑坡发生的概率,可为类似膨胀土的滑坡治理提供思路。

Swelling soil landslides pose threats to the safety of engineering construction.Affected by landslide hazards,hidden dangers with respect to the work safety are likely to occur during expressway construction,such as collapse of main works and fill,increasing gaps in surfaces and so on.Take the swelling soil landslide of an expressway as an example,causes were analyzed,and an engineering control scheme consisting of"slide-resistant piles+surface drainage system+slope drainage"was proposed based on engineering and geological characteristics,thereby reducing the likelihood of swelling soil landslides and providing a reference for the control of similar swelling soil landslides.
