安徽池州至安庆高速公路大渡口段软土路基工程地质研究(英文)

安徽沿江地区广泛分布的新近沉积软土,由于其埋藏厚度大、强度低、变形大、透水性低的工程特性而产生过大的路基沉降和路堤稳定性等工程地质问题,影响公路工程建设的质量和正常使用。本文对池州至安庆高速公路大渡口段软土路基的沉降和路堤稳定性进行了计算和工程地质评价。首先用分层总和法进行总沉降量计算,然后利用单向固结理论进行工后沉降计算。计算结果表明,软土路基工后沉降不能满足设计要求,须对其进行处理; 而填土路堤稳定性分析结果说明该路段路堤稳定。

Engineering Geological Research on Soft Soil roadbed in Dadukou Segment of Chizhou-Anqing Expressway in Anhui Province

The newly-built expressway can be destroyed because of deep soft soil in its roadbed, which is often the major reason for engineering geological problems. Based on the original data of geotechnical investigation, the authors conducted research on the roadbed, which consists of deep soft soil. It includes two parts: settlement calculation and slope stability analysis. The result showed that the settlement of the roadbed can't come up to the standard of design, so roadbed improvement is needed. But the embankment in this segment is stable.
