摘要
人工挖孔嵌岩灌注桩以其成本低、工期短、承载力高等特点而受到普遍欢迎,但与此同时,相对滞后的桩端持力层检验方法却在制约着它的发展,地质雷达的出现为解决这个矛盾开辟了新的思路。详细阐述了地质雷达的工作原理及应用,并结合"济南市广播电视技术中心"工程实测雷达图像对几种典型地质情况下的图像作出逐一释读。
This paper details working principle and application of geologic radar, explains images in several typical conditions by combining with radar images of “Jinan Broadcasting ＆ Television Technical Center” to enhance the knowledge of geologic radar for readers.
