自平衡静载试验在软岩地区桩基设计验证中的应用

摘要

In order to verify the design of rock socketed pile bearing capacity in soft rock strata, Test the side resistance and end resistance of the pile, using the self balanced static load technology on-site test. Assessment the actual bearing capacity of pile foundation, Obtain the pile side resistance and end resistance of the pile play characteristics With the increase of load.%为验证软岩地层的嵌岩桩设计承载力、实测桩周各土层发挥的侧摩阻力值和桩端阻力,采用自平衡 .静载试验技术进行现场试验.评估基桩的实际承载能力,取得嵌岩钻孔灌注桩随着荷载加大桩侧阻力和桩端阻力的发挥特性.
