超长钻孔灌注桩由于孔深较深,在施工过程中风险较大,易发生事故,本文结合几座特大桥的的施工实践,分析了发生事故的原因,提出了处理措施,对超长钻孔灌注桩的施工具有一定的指导意义。 Due to the deep hole depth, the super-long bored piles are more risky and prone to accidents in the construction process. Based on the construction practice of several large bridges, this paper analyzes the causes of accidents and puts forward the measures to deal with them. The construction of bored piles has some guiding significance.
