摘　　要：北坑水库及其配套输水工程是深汕特别合作区重点水源工程之一,输水线路总长度9.48 km,设计引水流量7.64 m^(3)/s,输水线路长,地形条件复杂,外部环境限制因素多,输水线路选择难度较大。为选取经济合理的输水线路,首先应根据供水规模,取、受水条件、地形地质条件、规程规范选定输水形式及输水方式。在此基础上,从实现功能、地形地质条件、工程布置、施工条件及工期、征地拆迁、生态环境影响、费用和效益等多方面对拟定的方案进行总体和局部的比较。经比选,西线1-1方案在工程地质条件、工程布置、征地拆迁方面不存在制约性因素,围岩地质条件较好,工期较有保障,工程投资较少,为最优线路方案。北坑水库输水工程输水线路选择研究可为类似工程设计提供经验和设计思路。The Beikeng Reservoir and Water diversion project is one of the key water source projects in the Shenzhen Shantou Special Cooperation Zone,the total length of the water conveyance line is 9.48 km,the design diversion flow is 7.64 m^(3)/s.The water conveyance line is long,the geological conditions are complex,and there are many external environmental limiting factors,the selection of water conveyance line is difficult.In order to selecting a economical water conveyance line,water conveyance type and method should be decided considering water supply scale,water supply conditions,geological conditions and relevant specifications firstly.Then,candidate water conveyance lines can be compared from fuctions,geological conditions,engineering layout,construction conditions,schedule,resettlement,ecological and environmental impact,cost and benefits.Based on comparation,The West Line 1-1 does not have any restrictive factors in terms of geological conditions,engineering layout,resettlement.In addition,the surrounding rock condition of West Line 1-1 is good,the time limit is relatively guaranteed,and the investment is relatively low.Therefore,it has been determined as the optimal water conveyance line.The analysis on selection of water conveyance line for Beikeng Water diversion project can provide experience and design ideas for similar engineering designs.
