A Review on Non-parallel Problem of Acoustic Pipes and Evaluation Methods of Pile Integrity in Foundation Pile Detection
摘要
Abstract
In foundation pile detection,it is necessary to evaluate the pile integrity.Cross-hole sonic logging is widely used in the field of foundation pile integrity detection due to its prominent advantages.In order to systematically understand and recognize the research progress and shortcomings of cross-hole sonic logging in the field of foundation pile detection,this paper firstly sorts out the relevant literature from 1997 to 2021,summarizes the main research contents and development history of cross-hole sonic logging in the field of foundation pile detection.The results show that the non-parallel problem of sonic logging pipe and the selection of pile integrity evaluation method are the key factors affecting the evaluation results of foundation pile integrity.Secondly,according to the logical sequence of first identification,then correction and last evaluation,the paper expounds the influence of sonic logging pipe non-parallelism on the evaluation results of pile integrity,analyzes the characteristics of acoustic parameter curves identification of sonic logging pipe non-parallelism being different from pile defects,and summarizes the types,principles,applicability,advantages and disadvantages of the sonic logging pipe non-parallel correction method and pile integrity evaluation method proposed by experts and scholars.The results show that the current correction method can only reduce the influence of the sonic logging pipe non-parallel phenomenon on the evaluation results but not eliminate it.Besides,the accuracy,operability and economy of the current evaluation method of foundation pile integrity are inefficient.Finally,suggestions are put forward that the non-parallel correction method of sonic logging pipe and the pile integrity evaluation method should be developed towards the intelligence due to the lack of research status and the development of technology,so as to be beneficial to the research of foundation pile integrity detection.关键词
