软基处理中填砂路段的汽车动荷载影响深度研究

通过整理测试汽车通过不同填砂厚度时应力变化情况,分析其变化规律,总结出汽车荷载对软基路段动荷载的影响深度。根据试验路段的实际情况拟合出车辆动应力与填砂厚度的经验公式,以此作为软基处理设计和施工中降低或消除汽车动荷载影响的理论依据。

Research of Influence Depth Load of Sand-filled Sections for by the Vehicle Dynamic Soft Foundation Treatment

When the vehicle pass through the sand with different filling thickness, the variation of stresses is tested. This paper analyzes the change rule of the stress and summarizes the influence depth of the vehicle dynamic load on the soft clay . In accordance with the actual situation, the rela- tionship of vehicle dynamic load and different filling thickness of sand is fitted into an empirical equa- tion, which can be used as theory basis of soft clay treatment design and construction measures to re- duce or eliminate the influence of vehicle dynamic load.
