一、前言一九六零年二月二十四日,青銅峽水利樞紐提前一天完成了截流工程。胜利截流标志着整个工程跨进一个新的施工阶段,它对保証今年开始灌溉、發电和整个工程提前竣工起着决定性的作用,同时也給在軟基上冰期截流,提供了宝貴經驗。本文只就个人体会写成,有待同志們和各兄弟單位的指正。 I. Preface On February 24, 1960, the Qingtongxia Water Control Project completed the river closure one day earlier. The success of the river closure marks the crossing of the entire project into a new construction phase. It plays a decisive role in ensuring irrigation, power generation and the completion of the entire project ahead of schedule this year. It also provides valuable experience in closure of ice sheets in soft ground. This article is written on personal experience, to be corrected by comrades and fraternal units.
