人工挖孔灌注桩桩长及持力层的确定

Determination of Supporting Course and Length of Artificial Drilled Piles

结合工程实际 ,以事实和数据为根据 ,并从理论上进行分析 ,说明了在进行人工挖孔灌注桩设计时 ,确定合适的持力层是很重要的 .结合工程实际情况 ,采用短桩 ,把持力层设在较浅的位置 ,可以降低工程造价 ,方便施工 ,缩短工期 。

A lot of data from the field experiences were collected and analyzed theoratically. The results demonstrated that it is important to select an appropriate supporting course during designing the artificial drilled piles. It will reduce the construction cost and take less time to finish the project and use short piles and set supporting courses at shallower positions than usual according to the field condition. The technology , which is convenient in construction, assures the construction quality.
