【摘要】：传统的大坝浇筑仿真模型大都使用基于数值的大坝形体模型，这需要大量的形体数据输入，同时形体数据提取过程相当繁琐，而且形体模型是由一些特征点拟合而来，精确性较差。本文基于对目前的混凝土拱坝浇筑仿真系统存在问题的分析，探讨了基于AutoCAD平台的混凝土拱坝浇筑仿真系统模型构建问题；运用.NET平台和AutoCAD自动化技术开发了混凝土拱坝的仿真平台。该平台将AutoCAD实体模型直接作为仿真平台中的拱坝的形体模型，同时将仿真结果在AutoCAD中演示，使仿真计算和结果可视化在同一平台下。因此，只要熟悉AutoCAD的设计人员就可以方便构建仿真模型，并进行仿真分析，提高了仿真模型构建效率和仿真过程的整体性。某工程对应其拱坝的坝体布置形式、两岸边坡条件以及国内缆机设备制造水平等综合影响确定了6台缆机，双平台布置的缆机布置方案。为了提高缆机效率，降低缆机吊深，供料平台采用不同高程双供料平台。以往高拱坝计算机仿真模型没有针对这种情况进行研究。本文针对该工程的施工方案的布置特点开展计算机仿真模型研究，研究该工程的基本浇筑规律，为浇筑方案的调整提供科学辅助手段。本文的主要研究内容为： 1、运用AutoCAD三维建模技术和计算机仿真技术建立了高拱坝三维实体仿真系统，利用AutoCAD中的功能模块，，可以构造包含工程信息的三维大坝实体模型，提高了建模效率； 2、针对该工程特点，对双缆机平台缆机调度与运用以及缆机运行期间的相互之间的干扰，以及双平台供料系统的运用等，进行了深入研究，提出了相应的仿真模型； 3、运用Visual Studio2008.NET平台的C#语言开发了高拱坝三维实体仿真系统。 4、不同方案的仿真结果进行对比分析，总结此工程中的大坝浇筑规律，为实际施工提供一定的指导，并提出合理建议。
[Abstract]:The traditional dam pouring simulation model mostly uses the numerical simulation model, which needs a lot of body data input, meanwhile, the extraction process of the body data is very complicated, and the shape model is fitted by some characteristic points. The accuracy is poor. Based on the analysis of the existing problems in the concrete arch dam pouring simulation system, this paper discusses the construction of the concrete arch dam pouring simulation system model based on AutoCAD platform. The simulation platform of concrete arch dam is developed by using. Net platform and AutoCAD automation technology. In this platform, the solid model of AutoCAD is directly used as the body model of arch dam in the simulation platform, and the simulation results are demonstrated in AutoCAD, so that the simulation calculation and the result can be visualized on the same platform. Therefore, as long as the designers familiar with AutoCAD can easily build the simulation model, and carry out simulation analysis, the efficiency of the simulation model construction and the integrity of the simulation process can be improved. According to the dam layout form of the arch dam, the slope condition of both sides and the manufacturing level of the domestic cable machine equipment, the layout scheme of six cable machines and two platforms has been determined. In order to improve the efficiency of the cable machine and reduce the depth of hoisting, the feed platform adopts different elevation double feed platform. In the past, the computer simulation model of high arch dam has not been studied. In this paper, according to the layout characteristics of the construction scheme of the project, the computer simulation model is studied, the basic pouring law of the project is studied, and the scientific auxiliary means are provided for the adjustment of the pouring scheme. The main contents of this paper are as follows: 1. The 3D entity simulation system of high arch dam is established by using AutoCAD 3D modeling technology and computer simulation technology, and the function module of AutoCAD is used. The 3D dam solid model containing engineering information can be constructed, and the modeling efficiency is improved. 2, according to the characteristics of the project, the scheduling and application of the cable machine on the double cable platform and the mutual interference between the cable and cable during the operation are discussed. And the application of the double platform feeding system, etc., has carried on the thorough research, proposed the corresponding simulation model; 3. Using C # language of Visual Studio 2008.NET platform, the 3D entity simulation system of high arch dam is developed. 4. The simulation results of different schemes are compared and analyzed, and the dam pouring law in this project is summarized. To provide some guidance for the actual construction, and put forward reasonable suggestions.
