| 摘 要： | 为弥补公路路堤沉降预测中各现有模型存在的不足,并有效控制高路堤在建设期的稳定性,提出了基于等体积法的路堤侧向位移沉降模型,并推导出了计算公式.采用该公式对高速公路试验段长达1 a的沉降和侧向位移观测数据进行分析计算.结果表明,由侧向位移产生的沉降量约占总沉降量的20%;侧向位移产生的沉降也并非瞬时能完成,也能延续相当长...

| Abstract: | In order to compensate the shortcomings of existing models for predicting settlement of highway embankment and to control the stability of high embankment construction effectivly,the model of embankment settlement with lateral displacement based on the equal volume method was proposed,and the formula was derived.The model and formula were used to analyse the measured settlement and lateral displacement of the test section of expressway in one year.The result shows that(1) the settlement caused by lateral di... |
