人工挖孔桩在粘性土中抗拔承载力的试验与分析

Test and Analysis of Uplift Ultimate Bearing Capacity of Manual Digging Piles in Cohesive Soil

现大多数城市建筑的基础采用人工挖孔灌注桩,其桩端土承载力参数的确定十分重要。本文通过人工挖孔桩的静载荷试验结果与两种计算公式的计算结果对人工挖孔桩在粘性土中的抗拔极限承载力进行对比和分析。

Nowadays, manual digging piles is adopted in the foundation of most of the city buildings, the determination of soil bearing capacity parameters of pile tip is very important. By static load test results of manual digging pile and calculation results with the two calculating formulas, this paper made comparison and analysis on uplift ultimate bearing capacity of manual digging piles in cohesive soil.
