既有线站场普遍存在排水不良现象,已成为运输安全中较突出的问题,现就这方面谈点看法。 一、站场排水存在的问题 站场排水在我国均按“设有倾向排水系统”的要求进行设计的,目的是使路基面的水能迅速排走,以保持路基面干燥,承载能力不至降低。具体设计一面坡、两面坡、锯齿形坡的横断面排除地表水。这一方法要求地表水横 Drainage has been widespread in both the existing line stations and has become a prominent issue in transport safety. Now we are going to talk about this point. First, the station drainage problems Station drainage in our country according to “have the tendency of drainage system,” the requirements for the design, the purpose is to make the subgrade water can drain away quickly to keep the roadbed dry, not carrying capacity reduce. Specific design of a slope, two sides slope, zig-zag slope cross-section excludes surface water. This method requires horizontal surface water
