拓宽路基差异沉降特性和影响因素

Widening Embankment Differential Settlement Characteristics and Influencing Factors

随着公路的车流量压力增大，我们需要对公路进行拓宽，但是在拓宽的过程中，由于土质的不同，拓宽后的新老部分会出现沉降，并且存在差异，我们应该从两方面对土质进行分析，包括路面下降的深度和水平移动的距离。

Along with the increasing traf ic pressure of high-way, we need to widen highway, but in the process of widening, because the soil is different, the old and new parts wil set le-ment after widened, and existing differences, we should analy-zes from two aspects of soil texture, including pavement de-cline depth and horizontal movement distance.
