隧道施工涌水处理方案及技术经济分析

铁路隧道工程涌水是施工中常见且容易造成严重后果的灾害之一，不仅影响隧道工程建设的正常施工，还会波及到隧道建成后的安全运营。此文以某特长隧道工程施工涌水为例，针对工程特点和施工组织设计。论述涌水处理方案及具体排水工作方式。并依据涌水处理方案进行技术经济分析，即抽水设备台班单价分析、抽水台班数量分析、某一段抽水总台班及费用分析，可为今后类似工程提供借鉴。

Scheme of Water Gushing in Tunnel Construction Scheme and Technical Economic Analysis

Water gushing in railway tunnel engineering construction is one of disasters that are common and easy to cause serious consequences, which not only affects the normal tunnel construction, but also spreads to the safety operation after completion of the tunnel. In this article, taking a specialty construction of tun- nel water gushing construction as an example, in view of the features of the project and the construction organization design, water gushing treatment scheme and concrete drainage mode are discussed. Then, the economic analysis is performed according to water gushing treatment project technical, i. e. , pum- ping equipment machine - team price analysis, pumping machine - team quantity analysis, pumping total machine -team and cost analysis, for future similar projects for reference, which will provide reference for future similar projects.
