摘要
大直径钻孔灌注桩广泛应用于高桩码头、长距离引桥等港口工程项目中,大直径钻孔灌注桩竖向承载力的设计不仅关系到结构自身的安全,同时也关系到工程的总体投资。通过国内行业标准与英标对大直径钻孔灌注桩竖向承载力的设计进行对比分析,在保证结构基础安全可靠的前提下寻求桩基入土长度的合理优化,最后通过静载试验结果对中英规范大直径钻孔灌注桩竖向承载力的设计进行复核。研究成果可为后续港口工程项目大直径钻孔灌注桩的设计提供一定的理论依据。
Large diameter cast-in-situ bored pile is widely used in high piled wharf, long distance approach trestle and some other port engineering projects. The calculation of vertical bearing capacity of large diameter cast-in-situ bored pile is not only related to the safety of the structure, but also related to project overall investment. After the comparative analysis of vertical bearing capacity design of large diameter cast-insitu bored pile between Chinese and British codes,we try to seek rational optimization of pile length under the premise of safe and reliable of structure,finally recheck the vertical bearing capacity of pile through the static test results. The research results can provide a certain theoretical basis for the design of large diameter cast-insitu bored pile in port engineering projects.
