基于塑料排水板处理软土路基的应用

Application of Soft Soil Subgrade Treatment Based on Plastic Drainage Board

针对软土路基压缩性强、稳定性差的问题,提出了塑料排水板处理方法,解决了软土路基施工中沉降明显、施工难度大等问题,达到了地基加速固结、强度提升的目标。结果表明:在塑料板水板应用中,通过铺设砂砾排水垫层、插入塑料排水带、铺设土工织物、填筑路基等方式,不仅可促进地基内水排出、土颗粒有效固结,还能够提高整体施工稳定性。

Aiming at the problems of strong compressibility and poor stability of soft soil subgrade,this paper puts forward the treatment method of plastic drainage board,which solves the problems ofobvious settlement and difficult construction in soft soil subgrade construction,and achieves the goal of accelerated consolidation and strength improvement of foundation.The results show that,in the application of plastic slab,laying gravel drainage cushion,inserting plastic drainage belt,laying geotextile and filling roadbed can not only promote the drainage of water in the foundation and the effective consolidation of soil particles,but also improve the overall construction stability.
