北京某下凹桥区排水系统建模研究

Building of Mathematical Model for Drainage System at an Underpass in Beijing

以北京市某下凹桥区排水系统为研究实例,利用InfoWorks ICM对桥区排水系统进行建模。梳理了桥区数学建模的流程,并对桥区一维管网模型、二维地面模型的构建以及旱天、雨天模型校核的方法进行归纳与总结,研究得到一种桥区数学建模和模型校核的方法和步骤,为其他桥区排水系统数学模型的建立提供了参考。

A mathematical model for the drainage system at an underpass in Beijing was built u- sing InfoWorks ICM. The process of the model building was investigated. The building of one-dimension- al pipe network model and two-dimensional ground model as well as the verification of dry and wet models were summarized. The methodology and procedures for building and verification of the mathematical mod- el were found to provide engineers with valuable data for building mathematical models for drainage sys- tems at other underpasses.
