【摘要】 糯扎渡水电站是澜沧江中下游梯级规划八座梯级电站中最大的水电站，其施工总布置牵涉到工程的各个组成部分，各部分施工本身亦随时间推进而不断变化，大量动态信息难以把握。为直观逼真地描述糯扎渡水电站施工总布置各环节间复杂的时空关系，本文对糯扎渡水电站施工总布置进行了三维动态可视化仿真与优化研究，研究成果主要体现在以下几个方面：1.以 GIS 为平台组织动态仿真数据结构，利用 GIS 特有的空间数据组织结构和 空间信息管理功能，系统研究施工总布置动态仿真数据可视化方法及实现。2.对糯扎渡施工总布置进行系统分析，运用大系统分解协调与控制理论，构造 一个包含六个子系统的糯扎渡工程施工总布置系统，将整个施工总布置系统 的仿真表现为各个子系统的仿真与协调耦合。设计了糯扎渡施工总布置三维 动态可视化仿真数据流向，实现三维动态可视化仿真演示。3. 结合 GIS 空间分析与处理能力，从空间位置上的约束条件出发，研究基于 GIS 的混凝土拌和系统场址选择可视化分析方法，为传统的施工总布置场址 选择提供新的思路和方法。利用 GIS 空间分析功能，对影响混凝土拌和系 统选址的各种空间因素进行可视化分析，通过叠加计算得出分析优选结果。 这一研究成果为施工场地选址提供科学决策的依据。4. 提出糯扎渡水电站施工总布置三维动态可视化仿真与优化系统具体开发途 径，设计了系统的体系结构，开发并实现了系统具体功能。为糯扎渡水电站 施工总布置组织设计与决策提供了强有力的分析工具。更多还原

【Abstract】 Nuozadu hydropower station is the biggest hydropower station among the eightstep hydropower stations to be built on mid-down stream of Lancangjiang River.Every component of the engineering is interfered with the construction site layout.Construction of every component is dynamically changing, thus it’s difficult to grasplarge amount of dynamic information. To intuitively and accurately describe thecomplex and dynamic spatial relationship among all sides interfered in constructionsite layout design of Nuozadu hydropower station, 3D dynamic visual simulation andoptimization for construction site layout of Nuozadu hydropower station is studied.The main contents and achievements of this thesis are summarily listed as following: Firstly, dynamic data structure is organized with the platform of GIS.Methodology and implementation of dynamic simulation data for construction sitelayout is studied by utilizing the special structure for spatial data organization andmanagement function for spatial information. Secondly, systematical analyzing is studied for construction site layout ofNuozadu hydropower station. Using the theory of decomposition-coordination andcontrolling for large system, the construction site layout system of Nuozaduengineering with 6 subsystems is built. Then the simulation of the whole constructionsite layout system is expressed with simulation and decomposition-coupling of allsubsystems. Flow of the 3D dynamic visual simulation data of Nuozadu constructionsite layout is designed, and then the 3D dynamic visual simulation demonstration andvisual inquiry of dynamic simulation data are realized. Thirdly, taking advantage of the spatial analyzing and dealing function of GIS,based on the constraints of spatial position, visual analyzing methodology of siteselecting for concrete mixer plant GIS-based is studied. Thus a new way andmethodology is provided for traditional construction site layout. Visual analyzing ofall spatial factors that influence the site selecting for concrete mixer plant is studied,and the optimum result is acquired after overlay computing. This result supplies ascientific support for construction site selecting. Fourthly, practical developing way for 3D dynamic visual simulation andoptimization system of Nuozadu hydropower station is presented, and the systematic<WP=4>structure is designed. System function is realized. The successful development of thesystem provides a forceful analysis tool for design and decision-making ofconstruction site layout of Nuozadu hydropower station.更多还原
