本文则基于对沧廊高速公路桥台台后土工格室柔性结构体系及地基的应力与变形监测数据分析和有限元分析,揭示了台后软弱地基上的土工格室加筋路堤及下部和周围地基的应力与变形规律,以及硬壳层地基上的土工格室加筋路堤的工作性状和硬壳层地基顶部的沉降与竖向应力分布规律,说明了土工格室柔性结构体系在高速公路硬壳层软基上处理路桥过渡段的应用是有效、可行的。
Based on the analysis of the stress and deformation monitoring data and the finite element analysis of the flexible structural system of the geocell and its foundation after the abutment of the Canglang Expressway, this paper reveals the geocell-reinforced embankment on the weak foundation of the platform and the lower part and the surrounding The stress and deformation of the foundation and the working characteristics of the geocell-reinforced embankment on the crust foundation and the settlement and vertical stress distribution at the top of the hard crust foundation, It is effective and feasible to deal with the transitional section of road and bridge on soft soil foundation.
