【摘要】 在我国修建水电工程,常会遇到地下厂房的设计问题。地下厂房是一个庞大的地下空间结构,洞室之间的空间关系错综复杂,地下厂房设计工作由初步设计到最终设计方案的确定经历多个阶段,设计方案需要反复修改,设计工作量大。影响地下厂房设计最主要的因素是地质条件,然而地下厂房一般都布置在高山峡谷中,地下厂房工程区域的地质条件往往十分复杂。二维的地下厂房设计方法,难以满足直观、快速、交互设计的需求。根据参数化设计原理,运用人机交互技术、参数化建模技术和数据库技术,基于三维地质模型,对地下厂房参数化设计理论与应用进行了深入研究,主要研究成果在于以下三个方面:(1)探讨了地下厂房参数化设计的相关问题,提出了地下厂房参数化设计的概念和基于三维地质模型的地下厂房参数化设计方法。地下厂房参数化设计包含了自顶向下和自底向上的设计过程;基于三维地质模型,通过对地下厂房参数化设计约束的识别、表达和求解,进行地下厂房位置、轴线方位和横断面的设计;基于三维建模的关键算法,构建地下厂房设计方案的三维模型。(2)针对地下厂房设计的复杂性和多样性,提出了地下厂房设计多方案优选方法。考虑到影响地下厂房设计的综合因素,构建了地下厂房设计方案的评价指标体系,通过计算地下厂房设计方案评价指标的权重,对地下厂房设计方案的相对优劣程度进行定量分析,为地下厂房设计方案的评价和优选提供了分析手段。(3)基于地下厂房参数化设计的理论与方法,研制开发了地下厂房参数化设计系统。通过用户需求分析,确定了地下厂房参数化设计系统的开发原则和目标,进行了地下厂房参数化设计系统的总体设计和功能设计,阐述了地下厂房参数化设计系统的应用流程,实现了地下厂房参数化设计系统的洞室轴线设计、洞室三维建模、设计方案分析和设计成果输出四个模块的功能开发,该系统在功能上满足地下厂房设计的基本要求。本文的研究是结合某抽水蓄能电站的地下厂房设计来开展的,地下厂房参数化设计系统具有重要的工程应用价值,有助于提高水电工程地下厂房的设计效率和设计水平。更多还原

Underground powerhouse is a large underground structure group with some anfractuous structures in space. There are some phases for design of underground powerhouse from initial design to final design. Design scheme is often amended repeatedly, and therefore much work is involved in design of underground powerhouse. Geological condition is the most important factor that impacts design of underground powerhouse. Underground powerhouse is often designed in the mountains. Geological conditions are often complicated in the region of underground powerhouse. 2D design of underground powerhouse has some limitations that it is difficult to design intuitively, quickly and interactively.
