太原地区后注浆灌注桩承载力估算分析

通过收集多项工程实例,对太原地区后注浆灌注桩桩侧阻、端阻及承载力提高系数进行统计、分析,得出本地区不同地层条件下的侧阻、端阻提高系数及承载力提高范围;提出太原地区合理、实用的后注浆灌注桩承载力估算公式,并通过实例验证,为本地区灌注桩后注浆设计、施工提供了参考依据,促进此项技术在本地区的推广、应用。

Bearing capacity estimating analysis on post grouting cast-in-place pile in Taiyuan

Through the collection of a number of project examples, this paper made statistical analysis on lateral resistance, tip resistance, bearing capacity improving coefficient of post grouting cast-in-place pile in Taiyuan, gained the lateral resistance, tip resistance improving coefficient and bearing capacity improving range of this area different stratigraphic conditions, put forward reasonable, practical post grouting cast-in-place pile estimating formula in Taiyuan, and through the example, provided reference for east-in-place pile design, construction in this region, prorooted the promotion application of this technology in local area.
