| 摘 要： | 依托徐州市城市轨道交通1号线某隧道，采用地质雷达对富水地层地下水及围岩裂隙发育情况进行超前探测分析，并根据探测结果对富水地层进行超前注浆。现场开挖与监测分析结果表明:通过地质雷达在隧道富水地层开挖过程中的有效地质预报，可以提前采取处理不良地质工程措施，为隧道顺利掘进创造有利条件。

Study on Treatment of Watery Strata at Subway Based on Geological Prediction with Geological Radar |
| |
| Abstract: | Based on a tunnel of Xuzhou urban rail transit Line 1, the development situation of groundwater and surrounding rock fissures in the watery strata was ahead detected and analyzed by GPR. and then according to the result of detection, the advanced grouting was carried out in the watery strata. The result of the excavation and monitoring conditions in the field shows that, by means of GPR geological prediction during tunnel excavation in watery strata, engineering measures may be adopted in advance against unfavourable geological condition and create favourable condition for succeed tunneling. |
