三峡库区港口码头排水关键技术

港口排水关键技术是港区码头稳定性研究的内容之一,也是库区防治地质灾害研究的主要方面。大量研究表明,水是岸坡失稳和码头结构滑移破坏的敏感因素。应用流体力学理论结合码头结构建设,分析了地下水排泄过程,借助管道和碎块石盲沟建立了港口码头快速排水与挡墙基床排水的方法;运用质量守恒定律和地下水渗流原理,建立了港口码头排水计算数学模型和排水过程计算公式,并用在了码头的稳定设计计算中。排水技术的研究对港口码头的稳定分析以及地质灾害的防治具有指导性意义。

Key Drainage Technique for Quay in Three Gorges Area

Port key drainage technique is a part of wharf stability research and a main aspect of study on prevention of geologic calamity in reservoir area as well.A large number of researches indicate that water is a sensitive factor of bank's losing stability and quay structure's slipping damage.This paper analyzes the groundwater discharging course using fluidics theory and combining quay structure construction;sets up the method of fast drainage by the dint of pipeline and blind ditch of fragment stone;and gives the computational mathematical model for quay drainage and calculation formula for drainage process according to the principle of conservation of mass and underground percolation,which have been applied for quay's stability design and calculation.The research on drainage technique is instructive for quay stability analysis and geologic calamity prevention and control.
