摘要
文章结合工程实际,利用有限元软件,对海堤拓宽工程中新老路基采用的不同软基处理方法进行模拟。结果表明,排水预压法工后沉降较小,但是在施工期间对老路的扰动较大,存在稳定性不足的情况;预应力管桩复合地基可以有效降低施工期间沉降以及工后沉降。
Combing with the seawall widening project, the road foundation with different treatment methods is simulated by finite element software. The results show that the settlement occured mainly in the construction period when using the preloading method, but it has greater impact on the old road and lack of stability. The settlement during construction period and after construction can be reduced effectively by composite foundation.
