工程物探中若干问题探讨

本文针对工程物探中主要任务与要求，着重讨论了查找陷伏断层，鹇基岩面及其风化壳的划分，第上系分层等问题，分析当前常用物控方法的有效性，探讨提高勘查能力，合理选用方法的途径，文中以直流电法，电磁法，声纳法和地震法等的应用实例进行对比，阐述它们的应用前提并对其进行评价。说明充分了解各工区的地质地球物理特征及工作前的方法技术试验是不容忽视的基础工作。

A RESEARCH ON A FEW PROBLEM IN ENGINEERING GEOPHSICAL EXPLORATION

This paper discusses the problem on hidden fault,primary formation surfaces and the distributon of their weathering crust deposits and Quaternary subdivision in order to solve the major task and requirement in engineering geophysical explortation, It also studies the effectiveness of the normal exploration methods, the way to improve exploring abilities and to choose the methods reasonably according to the geological and geophysical condition. With the comparison of electrical method, electromagnetic method, acoustic admittance and seismic methods, it is proved tnat the fully understanding the geological and geophysical character of every district concerned and the trial of the technical methods before work is the basic work that should not be neglected.
