摘要
从岩溶地质发展规律的角度分析了富水岩溶裂隙水的发展规律;研究了地质雷达电磁信号对岩溶裂隙水的反射特征和基于雷达信号的波速-介电常数关系的含水量估算方法;具体工程实例应用分析表明:地质雷达对隐埋在低含水量值的岩体中的裂隙水及裂隙岩体环境的分辨力良好,岩溶裂隙水含水量的估算方法可行。验证了基于地质规律认识的信号分析方法对岩溶裂隙水不良地质圈定和含水量估算方法的有效性。
The geological development principles of karst-fissure aquifer were analyzed.Then the characteristics of GPR electromagnetic reflection signal on karst-fissure aquifer and water content estimation method based on wave velocity-dielectric constant relationship were studied.Through specific engineering application,the geological radar has good resolution to fracture water buried in low water content rock and in fractured rock environments.And the estimation method of Karst fissure water moisture is feasible.The validity of the signal analysis method based on the geological understanding of the law to delineate adverse geological of karst fissure water and to estimate water content was verified.
