高强土工织物代替反压土体在软基施工中的应用

Application of High-Strength Geotextile Instead of Back Pressure Soil in Soft Foundation Construction

通洋高速TZ-1标段团结河大桥南侧桥头段为软土路基施工,在初步设计中,对软基处理时为保证路基稳定在路基两边使用了反压土体,后改用多层高强土工织物代替了反压土体,节约了大量的用地和时间,取得了很好的效果,为本标段重点控制性工程之一。

The bridge head section on the south side of Tuanhe River Bridge in the TZ-1 section of Tongyang Expressway is a soft soil roadbed. In the preliminary design, the soft foundation treatment is used to ensure the stability of the roadbed and the back pressure soil is used on both sides of the roadbed. After replacing the back pressure soil with multi-layer high-strength geotextile, it saved a lot of land and time and achieved good results. This is one of the key control projects for this tender.
