基于GPRMAX的隧道超前地质预报正演模拟与实测数据分析

摘要

Based on theory of propagation of electromagnetic waves ,we summed the universal law of a two - dimensional section of geological radar which is generated by the forward modeling based on GPRMAX .And the typical unfavorable geolog‐ic bodies are discussed during the process of tunnel excavation .We make the corresponding judgment about the measured geo‐logical radar data with reference to the results of the forward modeling ,and check the result of the judgment by a living exam‐ple .%以电磁波的传播理论为依据，总结了基于 GPRM AX2D 的地质雷达正演模拟生成的二维剖面图的一般规律，探讨了隧道掘进过程中遇到的典型不良地质体的雷达图像特征，依据正演模拟结果对实测地质雷达数据进行了相应地解译，并用开挖实例验证了解译成果的准确性。
