摘要
桩基工程桩属于隐蔽性工程,在其施工过程中存在着各种各样的不确定因素,比如混凝土离析、断桩、沉渣过厚及断桩等造成了桩基在工程施工中的质量问题。因此,桩基的完整性检测成为重要的质量评估指标。本文介绍了小波变换的基本原理,同时结合工程实际,利用小波变换理论,解释完整桩和有缺陷桩的典型波形特征。本研究结果对工程应用有重要的参考价值。
Pile foundation engineering pile is hidden engineering.There are various uncertain factors in construction,which cause the quality problems of pile foundation,such as concrete segregation,broken pile,too thick sediment and broken pile,and so on.The integrity detection of pile foundation has become an important quality evaluation index.In this paper,the basic principle of wavelet transform is introduced.At the same time,combined with the engineering practice,the typical wave characteristics of complete pile and defective pile are explained by wavelet transform.The research results have important reference value for engineering application.
