一、隧洞快速开挖的組織与施工(一) 循环作業指示图表的編制水工隧洞工程的施工組織与机械化的主要目的是尽可能在最短的期限内完成隧洞建筑,以便縮短整个水利樞紐的修建期限,并在这种情况下保証最低的工程造价、良好的質量和最大的安全性。为了完成这些任务,必須采用工程循环作業的組 First, the organization and construction of rapid tunnel excavation (A) preparation of circular operation instructions chart The main purpose of construction and mechanization of hydraulic tunnel construction is to complete the tunnel construction as soon as possible in the shortest possible time, in order to shorten the construction of the entire water control project Deadline, and in this case to ensure the lowest project cost, good quality and maximum security. In order to accomplish these tasks, you must use a group of engineering cycle jobs
