京哈高速公路绥中至沈阳段软基沉降分析

Settlement Analysis on Soft Soil Foundation of Suishen Expressway

软土地基上的高速公路改扩建工程,由于新旧路基间的差异沉降,易导致路面开裂破坏。结合绥沈高速公路改扩建工程,选取典型地质情况,分析了旧有路基的剩余沉降及新旧路基间的差异沉降,为高速公路软基段加宽方案选择提供部分理论依据。

Due to the differential settlement between the new and old subgrade, the reconstruction and expansion engineering of expressway on the soft soil foundation will easily cause craking damage to the pavement. In combination with the reconstruction and expansion engineering of Suishen Expressway, the the old subgrade and the differential settlement of the new and old subgrade are analyzed geological condition selected, partially providing theory for the selection of widening scheme section of the expressway. residual settlement of based on the typical of soft soil foundationsection of the expressway.
