【摘要】 考虑层状岩体和层状岩质基坑的特点,如何合理设计层状岩质基坑三维可视化系统是岩土工程界急需解决的一大科学难题。本论文以层状岩质基坑工程理论和三维可视化设计原理的研究为基础,以层状岩质基坑三维可视化系统的开发为研究内容,系统研究了层状岩质基坑开挖与支护的三维可视化设计理论,取得如下成果:（1）根据不同的组合划分层状岩质基坑的类型,确定层状岩质基坑的稳定性影响因素包括为三个方面。针对层状岩质基坑工程岩体失稳破坏的特点,提出了三种常用的支护结构并指出,对贵州岩溶地区层状岩质深基坑工程的支护,宜以普通锚杆与预应力锚杆（锚索）为主,并辅以其他支护方式。（2）引入面向对象的方法,深入探讨了三维可视化工具Visual C++的适用性,全面介绍了OpenGL的基础理论、工作原理及库函数与运行方式,制定了Visual C++下OpenGL的开发框架。（3）提出了层状岩质基坑三维可视化系统的总体设计思想和总体结构。结合层状岩质基坑三维可视化系统的功能要求及设计准则,开发设计了层状岩质基坑三维可视化系统的一般功能。（4）通过调用FLAC^3D软件,实现了层状岩质基坑的开挖和支护设计,提出了层状岩质基坑三维可视化系统的开挖模块和支护锚索模块的设计方法,初步实现了层状岩质基坑三维可视化系统的开挖和支护功能。（5）以层状岩质基坑三维可视化系统,实现了“世纪夏都·城市公园”基坑开挖的三维可视化,并调用FLAC^3D进行分步开挖与支护设计,实现了层状岩质基坑既“可视”又“可算”。本论文对层状岩质基坑三维可视化理论进行了较全面的研究。取得的成果,对发展层状岩质基坑三维可视化理论和支护设计理论有重要的理论意义、现实意义和较广阔的应用前景。更多还原

【Abstract】 It is an imperative scientific problem of geotechnical engineering should be resolved that how to consider the feature of the layered rock and the layered rock foundation pit, design the layered rock foundation pit of 3D visualization system. Based on the research of engineering theory of the layered rock foundation pit and the design principle of the 3D visualization, the paper studies the layered rock foundation pit in 3D visualization system. It systematicly studies the excavation of layered rock foundation pit and the design theory of the 3D visualization, results as follows.（1） According to the different types of the layered rock pit combination division,defmes that the impact factors of layered rock pit stability which has three aspects. To the characteristics of the layered rock pit of rock mass instability destruction, it takes three common shoring structure and points out that the Karst area in Guizhou Province layered rock deep foundation pit project shoring, and mainly fits for using the roof bolt and the inherent stress roof bolt, also choosing the other shoring ways.（2） The applicability of 3D visualization tools for Visual C ++ is drilled down in-depth by introducing object-oriented methods and a comprehensive introduction of the basis theory of OpenGL, working principle, the treasury, function and operation mode,is presented. Accordingly, the development of the OpenGL framework,under Visual C ++, is given.（3） This paper presents overall design ideas and the overall structure of the layered rock pit of 3D visualization system. According to the function requirements and design criteria of Layered rock pit on 3D visualization system, the general function is designed for 3D visualization system of layered rock pit.（4） By using FLAC^3D , the layered rock pit excavation and support design can be achieved, which put forward a method of 3D layered rock foundation excavation visualization system module and cable support module. It primarily achieves the 3D visualization system of the excavation and support functions of the layered rock pit.（5） According to the actual project, this paper, combine the layered rock foundation of 3D visualization system, realizes the 3D visualization excavation of " Century City·Summer Park ". Employing FLAC^3D, designs excavation and support by step. Finally implement the "visualization" and " computability "of layered rock pit.In this paper, it presents a comprehensive study of layered rock on 3D visualization theory. The achievement applied to actual projects, has vital theoretical and practical meaning of layered rock foundation of 3D visualization.更多还原
