长距离输水管线工程设计数学模型的建立及几个关键问题研究

STUDY ON ESTABLISHMENT OF MATHEMATICAL MODEL OF LONG DISTANCE WATER TRANSPORTATION LINE

本文提出了建立长距离输水管线数学模型进行管线模糊优化设计的方法,就系统建模过程中涉及的长距离输水管线的水力计算、结构计算、水力瞬变的计算、管材选择、管线的自控理论等几个关键技术问题进行了探讨,指出在我国制定长距离输水管线设计与施工国家标准已迫在眉睫,并建议在我国长距离输水管道中应尽快应用SCADA系统。

A design method based on fuzzy-optimization principle of the pipe parameters to establish the mathematical model of long distance water transportation pipeline (LDWTL) has been recommended in this paper. In discussing some key technical points in modelization of LDWTL such as the hydraulic and structural calculation of long distance pipeline, the selection of pipe materials and the mechanism of the pipeline automatic control etc the extremely urgent necessity to draw up the national design and construction standards for LDWTL has been indicated. Also to adopt the SCADA system for LDWTL as soon as possible in the country is suggested.
