摘要
针对高速公路拼接段新建路基施工后 ,以边载形式引起已建公路产生的附加沉降的不良影响进行研究 .应用土体固结非线性有限元法 ,利用原高速公路的监测沉降记录 ,对拼接地区的地基参数进行反馈分析 ,以确定能综合反映当地地基状况的参数 .方法在锡澄与沪宁高速公路拼接段上应用 ,经一年多的现场监测表明取得了良好的效果 .
The unfavorable effect of the new built foundation of the connection section is studied. By use of the observed settlement of the existing highway, feedback analysis of the foundation parameters at the connection section is performed with soil consolidation finite element method to determine the parameters reflecting the overall situation of the foundation. The method is applied to the connection section between the Xicheng and Shanghai Nanjing highways. Over one year field monitoring shows that the method is satisfactory.
