一九五五年五月,黄河三门峡水电站设计总地质师苏联专家В.И.萨维里也夫同志来三门峡工地检查工作时,对坝区主要钻孔的岩心作了详细的检查,并且要看岩心素描图。由于已往在工程地质勘察工作中,没有听说过要做这种图件,所以不能提供这项资料。以后专家曾再三指出这种图件为研究地下岩石工程地质特性的重要手段,并为水工建筑物基础设计依据之主要资料。因此专家为我们讲解岩心素描图的绘制方法。一年以来在三门峡水力枢纽工程地质勘察过程中,岩心素描图已被广泛采用,并作为一项主要地质
In May 1955, when comrades from the Soviet Union, the chief geologist of the Yellow River Sanmenxia Hydropower Station, visited the Sanmenxia site, Comrade Savile Yev made a detailed examination of the core of the major borehole in the dam and asked Look at the core sketch map. Since we have not heard of such drawings before in the engineering geological survey work, we can not provide this information. Since then, experts have repeatedly pointed out that this kind of map is an important means of studying the geologic characteristics of underground rock engineering and is the main material on which the foundation design of hydraulic structures is based. Therefore, experts explain to us the drawing method of core sketch map. During the geological survey of the Sanmenxia hydraulic junction project a year ago, the core sketch map has been widely adopted and used as a major geological
