灌注桩在填方边坡挡墙地基中的应用

The application of cast-in-place piles in the foundation of filling slope retaining walls

以福建省宁德市霞浦县某项目填方边坡支护为实例,对支护结构的选型、受力特性及设计方法进行分析,针对深厚软弱地基条件下挡墙支护设计的关键问题及解决方案,采用挡墙底设置灌注桩,承台梁连接挡土墙和桩的挡墙设计方案。监测数据表明,该方案在工程中得到了良好的应用效果,可为类似深厚软弱地基条件下的挡墙支护设计提供参考。

Taking the filling slope support of a project in Xiapu County,Ningde City,Fujian Province as an example,this paper analyzes the type selection,stress characteristics and design method of the support structure.Aiming at the key problems and solutions of the retaining wall support design under the condition of deep soft foundation,the retaining wall design scheme of setting cast-in-place piles at the bottom of the retaining wall and connecting the retaining wall and piles with the pile cap beam is adopted.The monitoring data shows that this scheme has achieved good application results in engineering,and can provide reference for the design of retaining wall support under conditions similar to deep and weak foundations.
