路基浸水对透水路面沉陷量的影响研究

为探究透水路面路基浸水软化后所造成路面和基层的沉陷行为，采用EDEM软件分析各层的沉陷量。模拟结果表明，浸水后的路基土，会在车辆荷载的作用下，造成上方的透水砾石嵌入路基土当中，使路面发生较大沉陷，且沉陷量几乎由砾石基层及路基土层所产生。

Research on Effect of Roadbed Flooding on Sinkage of Permeable Pavement

In order to explore the sinkage behavior of the pavement and subgrade caused by the softening of the permeable pavement roadbed, the EDEM software is used to analyze the sinkage of each layer. The simulation results show that the roadbed soil after flooded, the upper permeable gravel will be inlaid into the roadbed soil under the action of vehicle load, which makes the pavement large sinkage, and the sinkage amount is almost generated by the gravel base and roadbed soil layer.
