人工挖孔灌注排桩在基坑支护结构中的应用研究

通过对闽北山区土层采用人工挖孔灌注排桩在基坑支护结构中的研究、设计、施工、监测，较为成功地在山区土层中开发了人工挖孔灌注排桩基坑支护技术，摸索出一套适用于山区地基的基坑支护处理方法。该支护结构施工时不需要大型机械设备，操作工艺简单，施工工期短，支护结构刚度大、稳定性好，具有良好的止水性，坑内施工无空间障碍等优点，经济、社会、环境效益明显。

The Applied Research of Drilled Piles of Artificial Perfusion in Retaining Structure

Through adopting the Drilled pries of artificial perfusion in Retaining Structure to research, design, construction and monitoring of the sori on the north of FuJian, we successfully developed the techniques of Drilled piles of artificial peffusion in Retaining Structure in the mountain soil and explore a suitable mountain foundation pit support treatment. The support structure does not require large-scale construction machinery and equipments, What＇s more, there is lots of advantages, such as simple process in operation, short construction period, stiffness support structure, good stability stable,nice water resistance and no space barriers in pit construction etc. it has obvious benefits in Economic, social and environmental aspects.
