某工程嵌岩钻孔灌注桩大面出现Ⅳ类桩原因分析及处理方案

文章介绍某工程嵌岩钻孔灌注桩大面积出现Ⅳ类桩后，结构工程师对问题原因进行剖析，而后对实测桩身强度代表值不同的钻孔灌注桩给出针对性处理方案，可为今后类似工程问题提供借鉴和参考。

After a large area of Class IV piles appeared in a rock-socketed bored pile in a project, structural engineers analyzed the causes of the problems, and then proposed specific treatment schemes for bored bored piles with different representative values of measured pile strength, which can provide reference for similar engineering problems in the future.
