一、序言目前,我国正处在加速建设时期。因此,进一步提高地质勘探工作效果的问题,就向我们紧迫地提出来了。在水文地质和工程地质工作中应用地球物理勘探法中的电法勘探就能有效地达到这一目的。在苏联电探法已广泛地应用于水文地质工程地质勘探工作中。这是由于电探法在勘探中既能迅速取得所需成果又能给国家节省大批的财力。在实际应用中已获得一系列的成绩。由此可见,在我国电探法应当在水文地质和工程 I. Preface Nowadays, our country is in an accelerated period of construction. Therefore, the issue of further improving the effectiveness of geological exploration work is urgently raised to us. This can be effectively achieved by applying electrical prospecting in geophysical prospecting to hydrogeological and engineering geology. In the Soviet Union has been widely used in geophysical exploration engineering hydrogeology. This is due to the fact that geophysical prospecting can both achieve the required results quickly and save the country a great deal of financial resources. In practice has been a series of achievements. Thus it can be seen that geophysical prospecting in our country should be in hydrogeology and engineering
