摘　　要：长大隧道施工阶段的物探超前预报工作,是减少地质灾害、合理控制工效的重要手段。反射波法即为其手段之一。本文从该方法的理论入手,结合朔黄铁路长梁山隧道具体工程实例,详细分析了反射波法的动力学、运动学特点,介绍了外业布置方法、资料的处理流程以及采用该方法所获得的最终实效。对该方法的适用性进行了探讨,并就误差作了分析。The advance forecast with geophysical exploration for the construction of long and large tunnel is the important means to reduce geological disasters and to control work efficiency, and the method of reflected wave is one of the means. Based on the theory of the said method and the engineering practice for the Changliangshan tunnel of Shuohuang raliway, the characteristics of the dynamics and kinematics of the method is analyzed and the layout of the field work, the process of data and the actual effect by suing the method are intorduced. The applicability and the error of the method are discussed.
