Pile foundation comprehensive detection method based on initial stiffness method
The invention discloses a pile foundation comprehensive detection method based on an initial stiffness method. The pile foundation comprehensive detection method comprises the steps that firstly, somerepresentative pile foundations are screened from all pile foundations in a pile foundation site so as to construct a pile foundation standard library; secondly, after static load method testing tests and initial stiffness method testing tests are sequentially conducted on all the pile foundations in the pile foundation standard library, the bearing capacity differences, obtained through the twotesting methods, of all the pile foundations are compared so as to obtain the correction variable of the bearing capacity deviating from the actual bearing capacity of the pile foundations when the pile foundations are tested through the initial stiffness method; and finally, all the pile foundations in the pile foundation site are tested through the initial stiffness method, the bearing capacityobtained through the tests is corrected with the assistance of the correction variable, and the pile foundation bearing capacity detection precision is improved. According to the pile foundation comprehensive detection method, the technical difficulty of batch pile foundation detection is greatly lowered, and detection is simpler, more economical and more practical. Meanwhile, on the premise thatthe pile foundation detection efficiency is improved, the detection precision of pile foundation bearing capacity dynamic testing is improved.
本发明公开了一种基于初始刚度法的桩基综合检测方法，首先从桩基场地内的各桩基中筛选一些具有代表性的桩基，以构建桩基标准库；接着对桩基标准库中的各桩基先后进行静载法测试试验、初始刚度法测试试验后，比较各桩基经所述的两种测试方法所得到的承载力差异，以获得初始刚度法测试桩基时的承载力偏离该桩基实际承载力的校正变量，最后，采用初始刚度法测试桩基场地内的各桩基，并对测试所得到的承载力，辅以校正变量予以修正，提升桩基承载力检测精度。本发明大大减少了批量检测桩基的技术难度，检测更加简单、经济、实用。同时，提升了桩基检测效率的前提下，提升了桩基承载力动测的检测精度。
