摘　　要：论文详细介绍了旁孔透射波法的基本原理,并探讨了在不同介质中弹性波传播过程中的频谱响应特征差异。将频谱特征作为旁孔透射波的辅助判据,以改变首波初至时作为唯一判据的不足性,并通过工程实例应用分析,表明其可有效提高旁孔透射波测试成果的可靠性。In this paper,the basic principle of parallel seismic test is introduced in detail,and the frequency spectrum characteristics of elastic wave propagation in different medium is discussed.The frequency spectrum characteristic is used as the auxiliary criterion of side hole transmission wave in order to change the inadequacy of the first wave arrival as the only criterion,and the application analysis of engineering examples shows that it can effectively improve the reliability of side hole transmission wave test results.
