【摘要】：三峡库区库岸界桩测量与埋设,具有5大特点:①界桩测设涉及淹没实物指标补偿的敏感问题,按《长江三峡工程初步设计水库淹没实物指标调查大纲》的要求进行界桩测设,保持其一致性至关重要;②库周两岸长近6000km,涉及湖北省、重庆市的25个县(市、区),干、支流线路长,界桩测设工作繁重,且承担测量和埋设单位多,项目管理难度大,需要规范施工程序管理;③库区干、支流交错,合理布设界桩并保持其成果的统一,以达到既保证测设质量,又使成本开支最小,既考虑各区域的特点,又保证全库区的统一;④三峡库区地形地貌复杂,交通运输十分困难,施工环境差,界桩测量精度要求高,测量设备的先进性和测设人员经验、素质十分重要;⑤库区埋设界桩4万余座,且移民周期长,故界桩属永久的基础设施,界桩的管理任务艰巨
[Abstract]:The surveying and laying of boundary piles on the bank of the three Gorges Reservoir area has five major characteristics: 1. The boundary pile survey and installation involves the sensitive problem of compensation of the inundation material index. The boundary pile survey is carried out according to the requirements of the outline of the Survey of the inundation material Indexes of the preliminary Design Reservoir of the three Gorges Project of the Yangtze River. It is very important to maintain the consistency of the two reservoirs with a cross-bank length of nearly 6000km, involving 25 counties (cities, districts) in Hubei Province and Chongqing Municipality, long trunk and tributary lines, heavy surveying and setting up of boundary piles, and a large number of survey and laying units, which makes project management very difficult. It is necessary to standardize the construction procedure to manage the trunk and tributaries of the reservoir area, to arrange the boundary piles reasonably and to maintain the unity of the results, so as to ensure the quality of survey and installation and the minimum cost and expenditure, both to consider the characteristics of each region and to ensure the unity of the whole reservoir area. (4) the three Gorges Reservoir area is characterized by complex landform, difficult transportation, poor construction environment, high precision of boundary pile survey, advanced quality of surveying equipment and experience of surveyors, and the quality of which is very important to install more than 40,000 boundary piles in the reservoir area. And the migration period is long, so boundary piles are permanent infrastructure, the management task of boundary piles is arduous.
