Abstract

Using the typical section of semi-filled and semi-cut subgrade in the mountainous area of Guizhou, based on the GEOSEEP/ W program analysis of subgrade drainage problems, the seepage field changes under 48 hours of rainfall are simulated, and the seepage field and the subgrade in the subgrade are analyzed according to the rainfall time. Changes in pore pressure. Through the comparison of plastic blind ditch materials and crushed stone blind ditch materials. The simulation result shows that the water flow rate in the gravel blind ditch gradually decreases 6 hours after the beginning of the rain, but the water flow rate in the plastic blind ditch reaches the peak, and the water flow rate is much higher than the former, highlighting the superiority of the plastic blind ditch. It is of great significance for the plastic blind ditch material to effectively improve the drainage problem of the roadbed.
