摘要
通过对某高层建筑桩基工程钻孔灌注桩采用桩端压力注浆的工程实例,利用静载荷试验、沉降观测结果及确定单桩竖向承载力设计值等多种方法分析,表明桩端压力注浆钻孔灌注桩在中、粗砂混合层中的承载力得到显著的提高。
It has been shown that when the bored piles with pressure groutings at their tips are used in a mixed layer of medium and coarse sands,their bearing capacities would be increased evidently,according to the pile foundation of a tall building,where bored piles are used,using static loading test,the results of settlement observations as well as the determination of designed value of vertical bearing capacity for a single pile.
