摘要
本文通过１１根有埋设测试元件的现场试验，研究了软土地区人工挖孔扩底桩的荷载传递机理及侧阻力、端阻力的变化规律，文中统计和分析了３００根人工挖孔桩的静载试验资料，提出了承载力的计算方法和桩端常用土层的极限承载力取值范围。
The mechanism of load transmission and variation law of lateral resistance and tip resistance of artificial belled pile are studied through field tests.Data of static loading tests of 300 pieces of artificial belled pile are analyzed herein and calculation for bearing capacity and the range of ultimate bearing capacity value of soil layer at pile tip are proposed.
