To reduce and prevent mud pumping, meet with stand
3、ard bed drainage design, we must adopt rational material, technology, combined with the actual situation of the rational construction project and construction method, attaches great importance to bed construction technology, process, equipment, and the quality of research. In the process of construc

Due to the roadbed untidy, make outflow water, impervious layer formed by surface water and groundwater, clay, through train loads of vibration, extrusion and pump, ballast through mud, turned up mud pumping formation. The paper introduces the formation mechanism of pumping road, the road is a pumping multi-factor comprehensive effect. Insufficient thickness of ballast, soil
