软弱地基条件下的高填方边坡支护设计研究--以福州市晋安区某公共住房工程为例

Research on the design of high filling slope support on soft ground--Take a public housing project in Fuzhou Jin an district as an example

结合福州某永久性高填方边坡支护工程,对支挡结构的形式、受力特性以及方案选型设计进行分析,探讨软弱地基条件下高填方边坡支护设计的关键问题以及解决方案,提出了基底采用灌注桩,挡土墙和桩基础之间设置碎石垫层的重力式挡土墙设计方案。监测数据表明,该方案在工程中得到了良好的应用效果,为类似软弱地基条件下的高填方边坡支护设计提供了参考。

A systematic analysis is given for the structure form and mechanical characteristics and scheme selection of retaining structures with a permanent high filling slope support project in Fuzhou.The key problems and solutions of high filling slope support design on soft ground are discussed.The design scheme of gravity retaining wall with pile foundation and gravel cushion between retaining wall and pile foundation is put forward.The monitoring data shows that it is successfully applied to the retaining structures for a typical project in Fuzhou.The design of high filling slope support on soft ground may provide a reference for similar projects.
