水陆两栖工程物探新方法新技术

通过大量工程物探——大桥桥基探查,第四系探查,厂矿区地基探查,水库电站坝基探查,浅海海底沉积及基底探查等水上和陆地工作实践,对瞬变电磁法的基础理论、应用条件、方法技术、数据处理和成果解释等方面均有新的发展。在此基础上建立起以脉冲瞬变电磁法为主,辅以梳式电火花、浅层地震、声纳浅层剖面及常规电阻率法,适用于水上、陆地或水陆两栖工程物探的一套工作方法技术、数据处理系统和成果解释体系,使工程物探应用领域得以拓宽和深入。

NEW TECHNOLOGY AND NEW METHODS FOR ENGINEERING GEOPHYSICS USED IN LAND AND WATER AREAS

By a great many of engineering geophysics surveys worked on water orland areas:the explorations of the bridgebase, the quaternary overburden,the base of the factory sites and mining districts, the base of the hydro-power plant dam and the deposits of shallow seabed, some new technologiesand methods are developed in the TEM fundamental theory, the applicationconditions and technologies, the data processing, the result interpretationsand so on. On the basis of these applications, a system is establishedwhich mainly depends on the TEM method and is assisted by the comb-formed sparker, shallow seismic methods, shallow sonar profile methodand the convental electric resistivity method. The system includes thesurvey technology and method on land or water areas, the package of dataprocessing and the result interpretation methods. All these expand anddevelop the application areas of the engineering geophysics.
