京珠高速公路东西湖段软基处理数值分析

Numerical analysis on the treatment of soft clay in Dongxihu section of Beijing-Zhuhai Expressway

采用等效地基固结系数法,对京珠高速公路东西湖段软土地基,进行了比奥固结平面有限元分析。计算值与实测值比较接近。计算结果为选择地基处理措施和确定道面施工时间提供了依据,保证了竣工后该路段的工后沉降满足设计要求。

An equivalent consolidation coefficient has been employed for 2D-FEM based on the Biot consolidation theory to forecast the Dongxihus soil displacements for the Beijing-Zhuhai Expressway. The comparison between the predicted and measured values has proved that the constitution is reliable; the residual settlement was controlled effectively.
