摘要:
为了解土工格室处理高速公路拓宽结合部的效果,使加宽部分路堤和既有道路更为紧密地衔接形成整体,减少新老路堤的不均匀沉降,应用有限元分析土工格室铺于新老路基结合处不同层位时路基顶面各关键点的侧向位移、竖向沉降和最大差异沉降.结果表明,土工格室的铺设可以减少路基的侧向位移和差异沉降,且铺于基底和基顶时效果最好,可以提高路基整体刚度和地基承载能力.
Abstract:
In order to understand the effect of geocell in treating the widening joint of highway, so that the widened part of the embankment and the existing road are more closely connected to form a whole, and the uneven settlement of the new and old embankment is reduced, finite element analysis is applied to analyze the lateral displacement, vertical settlement and maximum differential settlement of each key point on the top surface of the subgrade when the geocell is laid at different levels at the junction of the new and old roadbed. The results show that the laying of geocell can reduce the lateral displacement and differential settlement of the subgrade, and the effect is best when laid on the foundation and the top, which can improve the overall stiffness and bearing capacity of the subgrade.
