一、概论本文是提出以积极的地下开发和合理的利用地下水为目的的地下坝的设想,并就其施工作报告。最近,工业用水的需要正急剧地增大,但其供给源年降雨量却是大致一定的,因而贮留降雨和水的合理利用就必然会成为问题。以贮留地表水为目的的河流坝,就我国这样的多山国家来说也未必是有利的,如,堤 I. INTRODUCTION This article is a proposal for an underground dam with the purpose of actively exploiting underground water and making rational use of groundwater and making a report on its construction. Recently, the demand for industrial water is rapidly increasing, but the annual rainfall of its sources of supply is roughly constant. Therefore, it is inevitable that the rational use of stored rainfall and water will become a problem. River dams aimed at reserving surface water are not necessarily beneficial to mountainous countries such as ours,
