Method for detecting and evaluating bearing capacity of socketed pile
The invention provides a method for detecting and evaluating the bearing capacity of a socketed pile. The method is used for detecting and evaluating abnormal foundation piles found through detection in the early stage of a project. The method comprises the steps that firstly, general detection is conducted according to the low strain method, a classification criterion is established based on the characteristics of the bottom of the socketed cast-in-place pile and the characteristics of a pile tip core sample obtained according to the core drilling method, the foundation piles in different types are selected to be detected based on classification and/or typical foundation piles are selected at certain proportion to be detected, and the detection method includes the high strain method and the single-pile vertical compression bearing capacity detection method. Analysis and statistics are conducted on various types of foundation piles according to the detection results, comprehensive engineering geological data and the statistical theory, the actual bearing capacity of the foundation piles is judged, and thus the bearing capacity of all the foundation piles of a unit project is effectively evaluated.
