引言钻孔灌注桩是桩基础中常见的一种基础形式,广泛应用于房屋建筑、水工建筑和桥墩基础的施工,具有施工速度快、占地少、相邻干扰少、承载力大等优点。但在施工过程中操作不当,很容易产生质量问题。根据我们多年的工程实践及观察,钻孔灌注桩在施工中的质量通病主要有:塌孔、斜孔、缩颈、断桩、桩身离析、钢筋 Introduction Bored pile is a common form of foundations, which is widely used in the construction of houses, hydraulic structures and bridge piers. It has the advantages of fast construction, less land occupation, less adjacent disturbance and large bearing capacity . However, improper operation in the construction process, it is easy to have quality problems. According to our many years of engineering practice and observation, the quality of bored piles in construction are: collapse hole, inclined hole, necking, broken pile, pile body segregation, reinforcement
