一、前言1955年8月苏联专家组审核了1954年以前三门峡的地质勘探资料以后,为了加速进行三门峡水利枢纽的技术设计工作,即提出应立即开始进行坝基帷幕灌浆试验工作。自1956年4月起至1957年2月止黄河三门峡地质勘探总队业已完成了第一和第二两个试验地段的任务;目前正在进行第三试验地段的工作。在上述这些工作中由于三门峡工程设计总地质师苏联专家 I. INTRODUCTION After the Soviet expert group reviewed the geological prospecting data of Sanmenxia before 1954 in August 1955, in order to speed up the technical design of the Sanmenxia Hydro-junction, it was proposed that the dam foundation curtain grouting test should be started immediately. Since April 1956 until February 1957, the Sanmenxia Geological Exploration Corps of the Yellow River has completed the tasks of the first and second experimental sites. The third experimental site is currently undergoing work. In the above work due to Sanmenxia engineering design chief geologist Soviet Union experts
