为了更合理地进行地震灾害评估，利用生命线地理信息系统（GIS）开发了一个管网模型自动化建模模块。该模块被分配了一个功能，该功能使得能够生成两种类型的分析模型，简单的2D模型和用于管道配置的高保真度的3D模型。该模块采用面向对象的程序设计方法，便于扩展生成其他类型的分析模型。将该模块应用于实际GIS中，验证了生成模型的配置性。作为实例，利用商用有限元软件包对自动构造的模型进行了数值分析，结果表明，这些模型具有力学上的一致性，可用于地震灾害评估。
This paper seeks to develop a module for automated model construction of a pipeline network using geographical information system (GIS) of lifeline, for the sake of more rational seismic disaster assessment. The module is assigned a functionality which enables to generate two types of analysis models, a simple 2D model and a 3D model with high fidelity for pipe configuration. The module is coded in an objective oriented programming, so that it is easier to be extended to generate other types of analysis models. The module is applied to actual GIS, and the configuration of the generated model is verified. As an example, numerical analysis is made for the automatically constructed models by using a commercial finite element method package, and it is shown that these models are mechanically consistent and can be used for seismic disaster assessment.
