Analysis of Mud-rock Flow Hydrological Calculation Songmugou Bridge and Its Design

泥石流是一种特殊的洪流,由于其流动时携带着大量泥、砂、石等固体物质,对铁路建筑物如桥梁、路基等建筑物形成极强的破坏力。该文结合岢瓦铁路宋木沟大桥处的泥石流成因、类型,详细地介绍了泥石流流量、水位计算,同时分析了泥石流对铁路桥梁设计的影响及设计中应采取的措施。

The mud-rock flow is a special kind of flood.Because of its flow with a lot of mud,sand,stone and other solid substances,it has the strong destructive form to the railway buildings such as the bridges and roadbeds.Combined with the cause and types of mud-rock flow at Songmugou in Kewa Railway,the article introduces in detail the flow of mud-rock flow and the calculation of water level,at the same time,introduces the influence of mud-rock flow on the design of the railway bridge and the measures that should be adopted in the design.
