地面车辆荷载对浅埋隧道影响的分析方法

Ways for Analysis of Impact of Ground Vehicle Loads on Shallow Tunnels

在城市浅埋的地下通道工程中,为考虑汽车车辆等荷载的作用,提出应用弹性半空间地基板模型对汽车车辆荷载向下传播规律进行分析。以深圳某地下通道工程为例,用该方法与目前地下工程设计中常用的汽车车辆荷载考虑方法进行了比较分析,认为该方法概念清晰,能够反映实际情况且计算简单,可作为车辆荷载对浅埋隧道影响的简化分析方法。

In the shallow urban underpass works of the city, it is proposed that the elastic half-space foundation plate model be used to analyze the rule of vehicle loads spread down. With the example of an underpass works in Shenzhen, a comparison is made between the new method and those with the car vehicle loads commonly used for the design of underground works now. It is thought that the new method is clear in concept, able to reflect the actual condition and easy for calculation, and can be used for a simplified analysis of vehicle load on the shallow tunnel.
