砾砂在公路软基排水垫层中的应用

Application of Sandy Gravel in Drainage Cushion Layer for Soft Road Foundation

对砾砂和中砂进行渗透试验研究及性能的分析,表明砾砂作为砂垫层在同等条件下,其力学性能和排水性能方面都有优于细砂,认证了在公路软基处理中用砾砂作垫层的可行性。

Seepage experimental studies and performance analysis on sandy gravel and medium sand have shown that both mechanics performance and drainage performance of sandy gavel as a drainage cushion layer is better, in the same conditions, than fine sands. The feasibility to use sandy gravel as the drainage cushion layer for soft road foundation is verified.
