摘要

结合大量实测资料和已有的研究成果，分析了路堤荷载作用下水平向应变随深度的变化规律，得出了侧向变形沿深度呈“弓”型分布的变化规律；提出了符合该变化规律的预测模型及参数求解方法，模型中a、b和c等3个待定参数能简单地求出。工程实践表明，该预测模型不仅反映了侧向变形随深度的变化规律，且有一定的精度，能反映出最大侧向变形发生的位置，应用效果良好。

Abstract

According to the distribution of horizontal strain in the soil under embankment loads

the characteristic of lateral deformations along the depth is analyzed based on measured data and existing research results. The results show that the typical curve is bow-shaped. On this point

the predicted model is established to forecast the lateral deformation. The three parameters in the model

b and c can be easily solved. This model has been applied to study 2 cases. The model can reflect both the distribution of lateral deformation along depth and the location where the maximum deformation occurs. The comparisons demonstrate that the predicted deformations are in good agreements with the measured data.
