摘要
以城市轨道交通站场路基工程为实例,阐述软弱土路基的特点,在存在软弱土地质的情况下,分别采用土工格栅铺设、砂垫层填筑、土工格栅处理及石灰土填筑的施工措施,解决了在不同地质、地形条件下城市轨道交通停车场地基沉降差异过大的问题,使路基承载力满足工程需求。
Taking the roadbed engineering of urban rail transit station as an example,the characteristics of soft soil roadbed are expounded.In the case of weak land quality,the construction measures of geogrid laying,sand cushion filling,geogrid treatment and lime soil filling are adopted respectively to solve the problem of large difference in ground settlement of urban rail transit parking lot under different geological and topographic conditions,so that the subgrade bearing capacity can meet the engineering requirements.
