某水利枢纽工程主体设计水土保持措施分析评价

The Analysis and Evaluation of Soil and Water Conservation Measures in the Primary Design of the Central Guizhou Water Conservancy Project

水利枢纽工程主体设计的水土保持措施分析评价对科学实施水利枢纽工程水土保持措施,进一步完善水库枢纽工程水土保持方案具有十分重要的意义。为此,结合贵州省黔中水利枢纽一期工程主体设计的水土保持措施分析评价典型实践案例展开分析。结果表明,在全面熟悉工程概况的基础上,首先着重围绕大坝枢纽区、永久办公生活区、施工生产生活区、道路工程区、料场区、弃渣场区、移民安置区及专项设施复建区等八个重点区域进行水源枢纽区水土保持措施分析评价;其次就渠线区、永久办公生活区、施工生产生活区、道路工程区、料场区与弃渣场区等六个主要区域实施灌区及贵阳供水一期工程干渠区水土保持措施分析评价;最后对灌区及贵阳供水一期工程支渠区的渠线区、施工生产生活区、道路工程区、料场区与弃渣场区等五个主要区域完成水土保持措施分析评价。可为类似水利枢纽工程主体设计的水土保持措施分析评价实践提供借鉴参考。

The analysis and evaluation of water and soil conservation measures in the primary design of water conservancy project hold significant engineering importance for the scientific implementation of such measures,as well as for further improvement of the water and soil conservation scheme of reservoir hub project.Therefore,the typical practice cases of water and soil conservation measures are incorporated into the primary design phase of the Central Guizhou Water Conservancy Project in Guizhou Province.The findings indicate that,on the basis of a comprehensive understanding of the project overview,first of all,the analysis and evaluation are focused on water and soil conservation measures in various areas including the dam hub area,permanent office and living area,construction production and living area,road engineering area,material yard area,waste yard area,slag disposal area,resettlement area and special facilities reconstruction area.The second aspect involves the analysis and evaluation of soil and water conservation measures in six key areas within the main canal area of Guiyang water supply projec,including the canal line area,construction office and living area,road engineering area,material yard area and waste dump area.Finally,the analysis and evaluation of water and soil conservation measures have been successfully completed in the five main areas of the irrigation zone,construction site,production and residential area,road engineering zone,material yard area and slag disposal area.It can serve as a valuable reference for the analysis and evaluation of water and soil conservation measures similar to the primary design of water conservancy projects.
