低路堤受交通动荷载作用的影响较大,需要合理确定地基处治深度,以减少路基动应力对路基的破坏。本文通过建立合适的低路堤车辆动荷载影响深度的数力学模型,对交通荷载作用下高速公路低路堤工程特性进行数值分析研究,得出高速公路低路堤地基处治深度及换填材料的强度要求,从而为低路堤的设计和地基处理方法提供依据。
The low embankment is greatly affected by the dynamic load of traffic, and the depth of foundation treatment needs to be determined reasonably so as to reduce the damage caused by subgrade dynamic stress on the subgrade. In this paper, the numerical model of low embankment affected by traffic load is established through the numerical model of low-embankment embankment affected by traffic load. The treatment depth of low embankment of expressway and the strength of filling material are obtained. Thus providing the basis for the design of low embankment and foundation treatment methods.
