| 摘 要： | 通过建立基于等体积法的路堤侧向位移沉降模型,推导出的计算公式能准确简便地计算出沉降组成中侧向位移产生的沉降量。采用该公式对某高速公路试验段长达1年的沉降和侧向位移观测数据进行计算,结果表明：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并非瞬时完成,而是延续相当长的时间;在沉降预测中,应充分考虑侧向位移产生的沉降对模型的影响。

| Abstract: | This paper deduces the formula,which can accurately calculate settlement composed of lateral displacement of the settlement based on the conatant volume method model for lateral displacement of the embankment settlement.Using this formula to calculate the settlement and lateral displacement observation data of a highway measured for 1 year,the result shows that the deformation of road embankment includes vertical settlement and lateral displacement virtually in the period of construction;the lateral displac... |
