铁路隧道智能辅助设计软件的研究与开发

摘要

根据铁路隧道设计业务需求和已有隧道辅助设计软件的现状，提出基于变量化设计技术和专家系统方法开发铁路隧道智能辅助设计软件的方案。介绍变量化设计技术和基于专业知识的智能化设计的原理和实现实质，研究隧道设计对象的组成构件的参数化特征，在对组成构件的5个方面的特征进行详尽描述的基础上，建立参数化特征模型和洞身衬砌标准库，开发铁路隧道辅助设计软件，实现隧道的智能化设计。该软件完成后已在多条铁路干线上进行应用，工程应用表明，技术方案是可行的，提升了隧道设计效率和设计质量。%This paper puts forward a solution of developing the intelligence aided software for the design of the railway tunnel based on variational design technology and the expert system according to design business requirements of the railway tunnel and current situation of existing tunnel design software. It introduces variational design technologies and principles and implementation of intelligence design based on professional knowledge and studies the parametric features of the members of the tunnel design objects. It also establishes the parametric feature model and the tunnel lining standard library on the basis of detailed description in five aspects of the members and develops aided railway tunnel design software to fulfill intelligence design of the tunnel. This software has been completed and applied to multiple railroad lines and the engineering applications show that this technical solution is feasible and improves the efficiency and quality of the tunnel design.
