摘要
文中以某软土路基为例,采用双曲线法、指数曲线法、三点法、Logistjc曲线法、Asaoka法对软土地基沉降变形进行沉降预测,为路基的安全稳定运营提供了重要参考,并提出控制路堤填筑的工后沉降量和预压时间等沉降控制措施,以期为类似的工程施工提供参考。
In this paper, a soft soil subgrade is taken as an example. Hyperbola method, exponential curve method, three-point method,Logistjc curve method and Asaoka method are used to predict the settlement deformation of soft soil foundation, which provides an important reference for the safety and stability of subgrade and operation. In order to provide reference for similar engineering construction, the settlement control measures of embankment filling should be strictly controlled, such as post-construction settlement and preloading time.
