摘要

通过理论分析与现场观测相结合，对京珠高速公路东西湖段软基沉降进行了分析。采用等效地基固结系数法，进行了比奥固结平面有限元分析，结合现场观测，及时对工后沉降进行了预测，并施加超载对工后沉降进行了控制。观测资料表明，沉降预测值与实测值比较接近，工后沉降得到了有效控制。

Abstract

Through the methods of theoretical analysis and field observation

the settlement of soft ground in Dongxihu section of Beijing-Zhuhai Expressway has been analyzed and controlled. Equivalent consolidation coefficient method has been employed for 2D-FEM based on Biot consolidation theory. Based on the observed data

the post-construction settlement was predicted and pre-compression measure was adopted to control the settlement. The predicted settlement is very close to the measured values; and it is proved that the prediction is reliable and the post-construction settlement has been controlled effectively.
