【摘要】 管道工程是城市生命线,大量管道位于城市道路下方,汽车荷载对管道的作用是管道受力计算的重要组成部分。随着城市发展道路改造的进行,许多道路改造时荷载升级。在这种情况下,原有地下管道安全成为必须考虑的问题。本文比较了各规范中不同车辆组合时汽车荷载作用下竖向土压荷载的标准值,提供一些参数供实际工程中参考使用。更多还原

【Abstract】 The pipe system is the life line of the city.Large quantity of pipe line was under the road.The car-load is the important element to calculate the pipe stress.With the development of city,the load of road has been increased.In this case,the safety of the old pipe line becomes a new problem must to be solved.With the comparison of the standards,different load-combinations were calculated and some useful parameters were provided in the paper.更多还原
