沉桩施工溜桩问题分析及解决措施

在码头桩基施工过程中,尤其是在软基条件下的沉桩施工,出现溜桩是一种常见现象.对溜桩产生原因进行分析,指出溜桩可能引发的各种问题,若对溜桩处理不当,会造成桩身裂缝、断桩等缺陷,严重时可能还会造成安全事故,在此基础上,结合具体工程案例,介绍了溜桩事前和事后所采取的解决措施,并进一步对解决措施进行检验,经检验,解决措施效果良好,可为同类工程提供借鉴.

Problems of rapid pile sinking during pile driving and solutions

The rapid sinking of pile is a common event during the piling execution at a port, especially the pile driving execution at the soft soil foundation. This paper analyzes the causes of rapid pile sinking and points out relevant problems which may be incurred. If the event of rapid pile sinking is not solved properly, it will result in many defects, such as cracks on pile, pile breaking, etc. Based on the analysis and practical project cases, this paper presents the precautionary measures and countermeasures to be taken for rapid pile sinking. Furthermore, it is prooftested that the solutions have good effects. Therefore, it is hoped that the construction measures and experience be used as references for similar works.
