一、概述葛洲坝工程拦截大江的截流工程,计划于1980底进行。截流难度较大,必须从各方面采取措施,以确保大江截流成功。按1974年建委座谈会决定:扩宽泄水闸,使截流落差不大于3米。据此进行设计与水工模试工作,取得了不少成果。1978年年初,召开的“葛洲坝工程大江截流及围堰技术设计讨论会”对大江截流方案进行了讨论。本文拟就葛洲坝截流提出一些个人意见,供参考。
I. Overview Gezhouba dam interception of the river closure project is planned to be carried out in the end of 1980. Closure is more difficult and measures must be taken from all quarters to ensure the success of the river closure. According to the 1974 Construction Committee forum decision: to expand the sluice, so that the closure of the gap is not more than 3 meters. According to the design and hydraulic mold test work, made a lot of achievements. In early 1978, the “Gezhouba Project River closure and cofferdam technical design seminar” discussed the river closure plan. This article intends to cut off the Gezhouba proposed some personal opinions for reference.
