Abstract

Roadbed pavement drainage design is an important part of road design, and subsurface drainage design is another difficult part of the whole drainage design. In this paper, the engineering example of mountainous highway is used to numerically simulate the actual highway seepage field by SEEP/W software for the concealed drainage design problem of highway roadbed based on unsaturated soil theory. Simulation results show that plastic blind trench has better drainage collection capacity than gravel blind trench. In highway engineering, plastic blind trench can be used as a kind of concealed drainage facility for roadbed with excellent performance.
