存车场火车轨道注浆效果综合物探应用研究
Study on Comprehensive Geophysical Application of Grouting Effect for Train Track in Storage Yard

地下注浆法可以进一步加固高速铁路地下工程结构，为初步探究济青高铁红岛站存贮车场的地下注浆系统情况，本文采用了高密度电法，电极的布设是一次进行的，避免了因电极的设定所带来的影响以及因此可能带来的测量精度误差。用高密度电法和探测地雷达两种检测方法都进行了有效探测。实验数据均表明，在距地下4 m深度左右时，高密度测线L1、电极L2没有出现过相对的高风阻情况，探地雷达出现了较明显减小的同相轴现象。通过与实际情况的比较，发现高密度电法探测和探地雷达在注浆区域都非常一致。
The underground grouting method can further strengthen the underground engineering structure of the high-speed railway. In order to preliminarily explore the situation of the underground grouting system in the storage yard of Hongdao Station of Jiqing High-Speed Railway, the high-density electric method is adopted in this paper. The deployment of the electrode is carried out at one time, avoiding the impact caused by the setting of the electrode and the possible measurement accuracy error. Both high-density electric method and detection ground radar detection method have been effectively detected. The data in the experiment show that at a depth of about 4m from the ground, the high-density measuring line L1 and electrode L2 have not experienced relatively high wind resistance, and the geodetic radar has a significantly reduced coaxial phenomenon. Through comparison with the actual situation, it is found that high-density electrical detection and ground detection radar are very consistent in the grouting area.
