沿海围垦区钻孔灌注桩施工出现的问题及防治措施

扫码查看
围垦吹填工程常常涉及厚度不均、低承载力的高压缩性海积淤泥和淤泥质粉质黏土,这些条件给超长钻孔灌注桩的施工、成桩质量和单桩承载力带来了挑战.本文通过具体案例分析,研究了沿海围垦区钻孔灌注桩施工过程中所遇问题,并在此基础上提出了针对性的防治措施.这些建议旨在为业界同仁提供有益的参考和借鉴.
Problems and Prevention Measures in the Construction of Bored Piles in Coastal Reclamation Areas
Reclamation and reclamation projects often involve highly compressible marine sediments and silty clay with uneven thickness and low bearing capacity,which pose challenges to the construction,pile quality,and single pile bearing capacity of ultra long bored piles.This article studies the problems encoun-tered during the construction of bored piles in coastal reclamation areas through specific case studies,and proposes targeted prevention and control measures based on this.These suggestions aim to provide useful ref-erence and inspiration for colleagues in the industry.
