复合加筋排水褥垫软土路堤排水设计方法

Drainage Design of Embankment on Soft Clay Deposit Improved by Combined Drainage with Reinforcement Cushion

复合加筋排水褥垫是针对沿海缺砂地区开发的一项可取代水平排水砂垫层、具有水平排水与加筋作用的新型专利技术。本文介绍了复合加筋排水褥垫的性能指标,给出了复合加筋排水褥垫软土路堤排水设计方法,并将复合加筋排水褥垫与水平排水砂垫层的排水性能进行了对比分析。算例结果表明,复合加筋排水褥垫能满足软土路堤排水要求,其排水性能要明显优越于水平排水砂垫层。

Combined drainage and reinforcement cushion is a patent technology, which can replace sand blanket in embankment construction on soft clay deposit. The material performance index of combined drainage with reinforcement cushion and the drainage design method are presented. The drainage capacity comparison between the sand blanket and the combined drainage and reinforcement cushion indicate that the latter has higher drainage capacity. Combined drainage and reinforcement cushion can meet the drainage request of embankment construction on soft clay deposit.
