水利工程施工期间的水流控制过程中,截流是一项关键性的施工环节。如果截流失败直接影响到工程进度,甚至使整个工期延期一年,会直接和间接地造成工程莫大损失。因此对每项工程,特别是大型工程截流设计和准备工作都留有余地,只准成功,不许失败。这样一来,在截流进行中,难免发生过于趋向安全方面,结果造成浪费。在一些工程截流总结中也都叙述了成功的经验,很少提到截流方面的成本问题。截流后所余
Water conservancy project during the construction of water flow control process, closure is a key construction link. If the closure of a direct impact on the failure of the progress of the project, or even to extend the entire duration of one year, will directly and indirectly caused a huge loss of the project. Therefore, every project, especially the closure and design of large-scale projects and preparatory work have left room for success, not allowed to fail. As a result, in the process of closure, it is inevitable that too much tendency to safety will occur, resulting in waste. In some engineering closure summary also describes the successful experience, rarely mentioned the cost of closure. After the closure of the rest
