钻孔灌注桩抗压承载力不足原因及处理措施

Reasons for Insufficient Compressive Bearing Capacity of Bored Pile and Treatment Measures

由于勘察方面工作不到位、设计方面的过失和施工方面的不规范等多方面原因,在钻孔灌注桩施工完成后进行承载力检测,经常会出现不满足设计要求的情况,造成灌注桩承载力不足,影响了工程的进展。基于此,总结了灌注桩承载力不足的常见原因,并结合分析结果提出了处理措施,为类似工程灌注桩承载力不足情况提供参考,保证施工的正常进行.

Due to various reasons such as inadequate survey,design mistakes and non-standard construction,bearing ca-pacity testing after the completion of bored pile construction often fails to meet the design requirements,resulting in insuf-ficient bearing capacity of bored pile and affecting the progress of the project.Based on this,the common causes of insuffi-cient bearing capacity of cast in place piles,the analysis of test results and treatment measures are summarized to provide reference for the situation of insufficient bearing capacity of cast-in place piles in similar projects and ensure the normal construction.
