土工格栅在道路拓宽工程中的应用研究

The Application Research of Construction Grille-Bar Used in Road-Widening Engineering

通过对已有高速公路拓宽工程进行研究,分析总结拓宽工程出现的主要病害形式及其原因,重点研究土工格栅处理加宽路基下软土地基的适用性、在处理新老路基结合部不均匀沉降中的作用及具体的工程措施设计。

On the basis of the survey of the widened highways that have been completed, main problems in these projects and the causes are analyzed, with the emphasis on the application of using construction grille-bar to deal with the soft groundwork when widening roadbeds, and on the effect of disposal of the uneven sedimentation in the joint parts of the new and old roadbeds and the detailed engineering measure designs.
