几年来,我国地质勘察工作中各种比例尺的地质测绘都按照统一定额,采用地质点工作法,提高了工作质量,但是,也有对地质点工作方法认识不足,使用不当的地方。仅根据工作中的点滴体会提出几个问题和意见。一、为“定点”而定点工程地质测绘中的地质点一般应定在:1.岩层,地貌之分界线上;2.地下水露头(天然的和人工的)处,有水文地质特征之地方;3.地质构造线上;4.具有工程地质意义之物理地质现象处;5.其他。
Over the past few years, all kinds of geologic surveying and mapping of geological prospecting work in our country have been based on a uniform quota and using the method of geological spot work to improve the quality of work. However, there are also places where the understanding of the working methods of the geological spots is inadequate and improperly used. Only based on the work of bit by bit experience to raise several questions and opinions. First, the “fixed-point” and fixed-point Geological mapping of geology in general should be located in: 1. Rock formation, topography of the dividing line; 2. Outcrop of groundwater (natural and man-made) at the place with hydrogeological features; 3. Geological structure online; 4. Physical geology with engineering geological significance; 5. Others.
