| 摘 要： | 为了准确的预测路基沉降,基于土基的固结理论,引入平均附加应力系数的概念,对路基沉降计算传统的分层总和法进行了改进;提出了考虑路基施工过程的路基最终沉降量计算理论与计算公式;建立了基于改进的分层总和法及实测的沉降量预测新模型;编制了基于改进的分层总和法和实测数据的路基沉降预测计算程序Settlement_Calculation;采用新的计算方法和计算程序,对安徽省某二级公路试验路段进行路基沉降观测和理论计算,得到的沉降预测值和实测值相对误差小于2.0%。

| Abstract: | In order to forecasting the embankment settlement accurately,based on the consolidation theory of soil,the additional stress factor is introduced to improve the traditional delamination summation-method of the total embankment settlement,and the improved calculation theory and formula are put forward.A new calculation and prediction model is built based on the improved delamination summation-method and practical survey.The calculation program Settlement_Calculation for the calculation and prediction of emba... |
