后压浆提高钻孔灌注桩承载力的初步研究(上)

Preliminary Study on Increasing Bearing Capacity of Bored Pile by Post Pressuregrouting

摘要:

依据有关理论及公式，通过对某地试桩结果及大量的地质资料和数据进行归纳整理，推导出一个在一定条件下的后压浆桩的单桩竖向极限承载力的计算公式，经与实际检测结果相比较，趋于吻合

Abstract:

Based on the relevant theory and formula, by summarizing the pile test results and geologic information and data, the calculating formula of vertical ultimate bearing capacity of single pile under given conditions is deduced. Through comparison it is proved that the formula tallies with the testing results.
