The influencing factors analysis of foundation fill height design

介绍了公路路基设计的三要素,着重从路线、桥涵构筑物、人与自然环境协调三个方面进行了分析,指出降低路基填土高度是今后高速公路设计的必然发展方向,高填路基只适用于地下水位较高或软土地基需抬高的路段,高填路基应慎重选用。

Three element factors of highway foundation design were introduced, which were analyzed emphasis on the route, bridges and culverts and coordination of human being with natural environment. It pointed that reducing foundation fill height was necessary development trend of future express highway design.
