1.序言在大型水工建設中机械化水平一般是很高的,但在当地条件下如果利用人工比较有利,則应考慮利用現有人力施工的可能性来进行机械化。在施工中人王所不能实现的繁重工序,应实行机械化。同时应当指出。在水利樞紐建設方面,施工的任何实物工程量都只是說明工程在时间上的規模。在二十世紀不考慮时间因素是不可以的。重要的是在最短时间內完成較大的工程量,因为水利樞紐有效利用的开始时間是由水輪發电机的起动时间来决定的。水輸發电机起动的时間愈早,水利樞紐工程一次投資的补偿就愈快。因而
1. Preface The level of mechanization in large-scale hydraulic construction is generally high, but if local conditions make it more advantageous to use manpower, then the possibility of using existing manpower construction should be considered for mechanization. In the construction, the heavy work that cannot be achieved by the king, should be mechanized. At the same time should point out. In the construction of water conservancy hubs, any physical quantity of construction work only indicates the scale of the project. It is impossible to ignore the time factor in the 20th century. It is important to complete the larger amount of work in the shortest time, because the start time of effective use of the water control hub is determined by the start-up time of the hydro-generator. The earlier the water generator starts, the faster compensation will be for a water conservancy project. thus
