摘　　要：挤压边墙作为面板与垫层料之间的过渡层,在面板混凝土施工之前,需要对挤压边墙与垫层料之间进行脱空检测。本文结合工程实例阐述了利用地质雷达技术对挤压边墙脱空检测的基本原理、图像特征、工作布置、参数选取等,并用开挖验证方式证明了地质雷达法在该领域的有效性与可靠性。The squeezed side wall is the transition layer between the panel and the cushion material.Before the construction of the panel concrete,it is necessary to carry out the void detection between the squeezed side wall and the cushion material.In this paper,the basic principle,image feature,work arrangement and parameter selection of the detection of the squeezed side wall by geological radar technology are expounded with engineering examples,and the validity and reliability of geological radar method in this field are proved by excavation verification.
