摘 要:我国现有的大多数铁路系统,从路侧边坡到挡土墙,都遭受了排水不良引起的故障问题。为此,进行了一系列实验室模型实验,以研究流量以及排水装置的最佳安装角度,并对排水装置和常规穿孔PVC管在多次干湿循环作用下的长期性能进行了评价和对比。结果表明,在定水头实验过程中,随着排水装置安装角度从0°增加到15°,新型排水装置内的流量先增大,再从15°增加到60°期间减小,在铁路路堑边坡中安装该新型排水装置时,建议倾角为5°~15°。Most of China's existing railway systems,from roadside slopes to retaining walls,have suffered from failures caused by poor drainage.To this end,a series of laboratory model experiments were conducted to study the flow rate and the optimal installation angle of drainage devices.The long-term performance of drainage devices and conventional perforated PVC pipes under multiple wet dry cycles was also evaluated and compared.The results show that during the constant head test,as the installation angle of the drainage device increases from 0°to 15°,the flow rate inside the new drainage device first increases,and then creases from 15°to 60°.When installing the new drainage device in railway cutting slopes,it is recommended to have an inclination angle of 5°to 15°.
