地质雷达在隧道初衬质量检测中的应用研究

运用无损检测，对隧道初衬进行快捷、准确、有效地检测是现代隧道建设的重要部分。虽然地质雷达在隧道检测中使用较长时间，但操作人员经验不足，导致不能对采集的图象进行准确的判断。以山东青―莱高速公路隧道初衬检测为例，系统地介绍了地质雷达的原理和常见图像的识别判断，如空洞、不密实、衬砌厚度，锚杆、钢筋网和钢拱架间距。可以为操作人员积累经验和提供借鉴有重要意义。

Research on application of GPR to quality detection of first lining of tunnel

Nondestructive examination to first lining of tunnel is a fast accuracy effective method and an important part of tunnel construction.Although the ground penetrating rader(GPR) has been used for a long time in tunnel detection,the operators are scarce of enough experience so that they are unable to judge and analyze the collected pictures exactly.The principles and judgment of GPR are introduced systematically as an example of first lining detection of road tunnel of Shandong Expreessway,such as cavity,non-...
