| 摘 要： | 公路高路堤填筑期的变形包括竖向沉降变形和侧向位移.建立了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的计算出沉降组成中侧向位移产生的沉降量.采用该公式对兰许高速公路试验段长达1a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也并非瞬时能完成,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: | The deformation of road embankment includes vertical settlement and lateral displacement virtually in the period of construction. Based on the conatant volume method model for lateral displacement of the embankment settlement, the formula deduced can accurately calculate settlement composed of lateral displacement of the settlement. Using this formula to Lan-Xu highway measured for 1 year of settlement and lateral displacement observation data calculation result shows： the lateral displacement of the settlement accounts for about 20% of the total settlement, the lateral displace- ment settlement is not instantaneous, the process can continue for a long time. In the settlement mod- el subsidence prediction, full consideration should be given of lateral disnlaeement |
