摘要
介绍了温州世贸中心钻孔灌注桩工程施工过程中所采用的钻进工艺,简述了复杂地质条件下超深大直径钻孔灌注桩施工易发生的问题。根据工程实践经验,分析总结了施工过程中常见的工程事故及产生的原因,提出了施工中应采取的技术措施。
The drilling method in the construction process of bored piles sited at Wenzhou World Trade Center is introuduced in this paper. The accidents that happened in the construction of super deep large diameter bored pies under complex geological conditions arc briefly stated. On the basis of the in situ experience, the factors causing these accidents are summarized and some appropriate technologic measures are suggested. Some useful information for solving construction problems is described so as to provide engineering experience for the similar projects in the future.
