陆地声纳法的原理及其在铁路地质勘测和隧道施工中的应用

The Principle and Application of Landsonar Method in Railway Geological Survey and Tunnel Construction

为了适应浅层地质勘查以及在裸露岩面上也可布置检波器，综合地质雷达、地震反射法、声波法、水声法等物探方法的特点，研究实现了“陆上极小偏移距高频弹性波反射连续剖面法”，简称“陆地声纳法”。这种新的物探技术具有干扰波少、图像简单、反射波能量大等特点。本文介绍了基本原理，并介绍了在若干个工程中的成功应用实例，展示了这一方法的某些特长。

On the basis of georadar,seismic reflection exploration, ultrasonic wave methodand sonar method,we have developed the Landsonar Method featuring elastic reflectionwave of continuos profiling with high frequency and very short source-detector distance,Thenew method has some specialties such as low noise waves, simple images and higt energy ofreflection waves.In the paper the author described the basic principle and sorne successfulengineering examples which serve to show some characteristics of this method.
