人工挖孔桩施工技术应用

摘要

Combining with specific engineering examples,the paper introduces construction technology procedures of artificial bored pile,sum-marizes its construction methods from aspects of orientation sampling,earthwork excavation and steel installation,and finally points out that:ap-plying artificial bored pile construction technology can effectively solve poor building foundation bearing capacity,poor seismic performance,large amount of subsidence and other problems.%结合具体工程实例，介绍了人工挖孔桩施工的工艺流程，从定位放线、土方开挖及钢筋安装等方面，对其施工方法进行了归纳总结，指出该工程采用人工挖孔桩施工，有效解决了建筑物地基承载力不足、抗震性能差、沉降量大的问题。
