摘　　要：混凝土预制桩是我国当前应用广泛的基础形式,但由于各地工程地质情况的复杂性及该桩型固有的工程属性,在实际项目中,因设计、施工等主客观因素导致经常出现工程事故。从3个不同的具体工程事故案例出发,结合地质情况、事故状况及检测数据等条件,分析其发生的原因并采取有效的补救处理措施,并就工程中如何安全合理地应用混凝土预制桩提出针对性的预防措施。Precast concrete pile was widely used as the basic form in China,but the complexity of engineering geology and the inherent engineering attributes of the pile type,engineering accidents often occur because of the design,construction and other reasons in actual projects. According to 3 different specific engineering accident cases,combined with geological conditions,accident conditions and test data,the causes of the accident were analyzed and effective remedial measures were taken. The paper put forward the corresponding preventive measures about how to apply precast concrete pile safely and reasonably.
