【摘要】 <正> 平谷地区(包括平谷县及其毗邻地区)过去是个山多水缺、多灾低产的地方。解放后进行了大规模的水利建设,已基本控制了山洪,并扩大了水浇地面积,但山区水利条件仍较差。为了配合平谷县水利化运动,从七四年以来,我们和水文一大队同志一起开展了山区农田供水水义地质勘察工作,在运用地质力学方法找水方面取得了一定成效,并对平谷地区构造体系控水规律有了一些初步认识,现简述如下。更多还原

【Abstract】 On the basis of the data from a hydrogeological survey in the recent years, the authors have studied the networks of groundwater controlled by tectonic systems in the Pinggu mountainous district. This paper consists of the following parts: 1. A brief account of tectonic systems in this area. 2. The relation between the crack water of bedrock and the tectonic systems. 3. The patterns of the networks of ground water controlled by the tec- tonic systems. 4. The rule of enrichment of ground water in connection with the texture planes of different mechanical properties. 5. Brief conclusions. In this paper we try to apply the geomechanics theory to the explana- tion of the regional characteristics of ground water and the classification of the networks of ground water. lt is very important to study this topic, as the investigation has theoretical and practical significance. Of course, there are further works to be done.更多还原
