- Abstract:
-
The roadbed on the weak foundation is often carried out by rolling construction, which may lead to the lag phenomenon of horizontal and vertical deformation stability after construction, which seriously affects the construction progress of the entire highway project. Aiming at the high-fill treatment project of soft subgrade in the Dongxihu section of Beijing-Zhuhai Expressway in Hubei Province, the engineering effect and mechanism of different treatment methods of high-fill soft foundation of expressway were analyzed through the comparison test of the post-treatment effect of small piles without sand concrete and the settlement deformation curve during the construction of lightweight material subgrade, which has certain engineering reference significance.
