摘要
某项目高强预应力管桩沉桩施工中遇到强风化泥岩中存在中风化夹层的情况,采用引孔打桩法沉桩但出现竖向裂缝,文中对该问题进行分析并采取相应的技术措施,同时也发现生产中存在的质量问题。
The method of guilding-hole piling was taken in pile driving in the project The causes of verticle cracks on PHC tube-piles in strongly-weathered mudstone with moderately-weathered mudstone layers are analyzed in this paper. Accordingly,the technical measures to solve the problem are taken. Simultaneously,the quality problems are found in production.
