上海高速公路路堤总沉降及影响因素分析

Overall Settlement of Expressway Embankments in Shanghai with Analysis of Its Affecting Factors

整理分析上海地区沪嘉、莘松、沪宁及沪杭等高速公路路堤总沉降的实测成果,得到总沉降与路堤高度的关系,分析了天然地基条件和地基处理措施对总沉降的影响。提出以实测成果得到实际总沉降与理论总沉降的比值,作为上海高速公路路堤沉降计算修正系数,并说明了其适用条件和选值范围。分析结果对高速公路路基设计具有参考意义。

From collation and analysis of the overall embankment settlement actually detected of expressways from Shanghai to Jiading, Nanjing and Hangzhou, or from Xinzhuang to Songjiang, etc., the relation between the overall settlement and the embankment height is obtained. The impact from natural conditions of the ground and measures for ground treatment on the overall settlement is analyzed. It is proposed that the ratio of the actually detected overall settlement to the theoretical overall settlement be used for the correction factor in calculation of the expressway embankment settlement in shanghai, with notes to applicable conditions and range of values selected.
