Study on the Application of Crosshole Sonic Logging in Pile Foundation Detection
摘要
Abstract
Aiming at the identification of pile foundation integrity by crosshole sonic logging,the comprehensive application of three testing curves in defect identification was studied through theoretical analysis and field testing.The results show that:The crosshole sonic logging can effectively identify pile foundation defects and has broad application prospects;An analysis was conducted on the three types of testing curves,and a method for identifying defects through curve changes was obtained.Field testing has proven that the method is reliable;The crosshole sonic logging is less limited by the length and diameter of the pile.During the testing,a comprehensive analysis of the three types of curves should be conducted in conjunction with construction records to identify the types and scope of defects;During the construction process,the sonic logging may tilt,which causing the wave velocity and amplitude to remain within the critical values when there are defects.In this case,it is necessary to identify defects based on PSD anomalies.关键词
