摘　　要：弃土场具有结构松散、成分混杂等特点,设计阶段需综合考虑弃土体性质和弃土场基底条件,采取相应的边坡防护、支挡、排水工程措施,以保证弃土场的稳定,避免弃土场失稳引起的地质灾害。本文以某山区铁路弃土场为例,对弃土场边坡稳定性、支挡结构稳定性、排水系统合理性进行检算,结果证明该弃土场在天然和暴雨工况下边坡整体和内部均稳定,支挡结构抗滑移、抗倾覆稳定性和基底应力满足规范要求,排水系统能够满足排水要求,弃土场设计满足稳定要求。The abandoned soil site has the characteristics of loose structure and mixed composition.In the design stage,it is necessary to comprehensively consider the properties of the abandoned soil and the foundation conditions of the abandoned soil site,and take corresponding slope protection,support,and drainage engineering measures to ensure the stability of the abandoned soil site and avoid geological disasters caused by instability of the abandoned soil site.This article takes a railway spoil ground in a mountainous area as an example to calculate the stability of the slope,the stability of the retaining structure,and the rationality of the drainage system of the spoil ground.The results show that the slope of the spoil ground is stable as a whole and inside under natural and rainstorm conditions,the stability against sliding and overturning of the retaining structure and the stress of the base meet the specification requirements,the drainage system can meet the drainage requirements,and the design of the spoil ground meets the stability requirements.
