摘要
弃土场是一种巨型人工松散堆垫体,作为工程建设中不可或缺的附属设施,其稳定性问题随着我国基建规模的持续扩大日益凸显。相关研究以四川山区高速公路弃土场为例,根据设计规范要求,通过科学量化分析堆填参数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,结果表明,弃土场在天然、地震、暴雨三种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。希望相关研究对山区高速公路弃土场的设计起到参考作用。
The abandoned soil site is a giant artificial loose cushion body,which is an indispensable ancillary facility in engineering construction.The stability issue has become increasingly prominent with the continuous expansion of China's infrastructure scale.Taking the spoil ground of expressway in mountainous area of Sichuan Province as an example,according to the requirements of design specifications,the stability of spoil ground slope,stability of retaining structure and rationality of drainage system are checked and calculated through scientific quantitative analysis of filling parameters.The results show that the spoil ground slope is stable as a whole and internally under three working conditions of natural,earthquake and rainstorm;The anti slip,anti overturning stability,and foundation stress of the supporting structure meet the requirements of the specifications;The drainage system can meet the drainage requirements.I hope it can serve as a reference for the design of abandoned soil sites on mountainous highways.
