为了更有效的控制道路软基的沉降,在轻质路堤的基础上进行了填料和结构优化,探索出一种新型轻质结构路堤。该方法的核心思想是采用轻质材料作路堤填土,并在填料中加入钢管,提高路堤填土材料强度,从而减少公路软基的沉降变形。通过理论计算和有限元数值模拟方法研究,分析比较得出新型轻质结构路堤的沉降控制效果比轻质路堤明显,表明新型轻质结构路堤对软基沉降控制具有一定的合理性。
In order to control the settlement of road soft foundation more effectively, the packing and structure optimization based on light embankment was explored, and a new lightweight structural embankment was explored. The core idea of this method is to use light materials for embankment filling, and add steel pipe into the packing to improve the strength of the embankment filling material so as to reduce the settlement deformation of highway soft foundation. Through theoretical calculation and numerical simulation of finite element method, it is concluded that the settlement control effect of the new light-weight embankment is more obvious than that of light embankment, which shows that the new light-weight embankment has certain rationality for the settlement control of soft foundation.
