为提高斜撑桩极限承载力自检效率,提出了新的自检检测方法—-超快速维持荷载法(简称"超快速法"),结合工程实例对相同设计参数斜撑桩的"超快速法"与"快速法"Q—S曲线进行了对比分析;除此之外,对同一根斜撑桩采用"超快速法"与"快速法"先后检测的 Q—S曲线进行了对比分析.分析结果表明:"超快速法"与"快速法"检测结果基本相近,两者偏差为0~8.7%;"超快速法"经验证可行且检测结果可应用于工程实际.
Comparative analysis of the application of self-inspection and testing methods for inclined strut pile bearing capacity
To improve the self inspection efficiency of ultimate bearing capacity of inclined strut piles,this paper introduces a new self inspection method,known as the ultra-rapid load-maintaining method(referred to as the"ultra-rapid method").The Q—S curves of"ultra-rapid method"and"rapid method"for inclined strut piles with the same design parameters are compared and analyzed with engineering examples.Additionally,the Q—S curves of the same inclined strut pile inspected in sequence by"ultra-rapid method"and"rapid method"are compared and analyzed.The analysis results indicate that the inspection results of"ultra-rapid method"and"rapid method"are basically similar,with a deviation of 0-8.7%.The"ultra-rapid method"self-inspection and testing methods is verified to be feasible and the inspection results can be applied to engineering practice.
