摘　　要：在城市燃气管网的设计过程中,水力计算是最关键的环节。以往采用传统的手算平差法,存在计算周期长、误差大、计算结果保守的缺点。采用Visual Basic5.0开发了城市燃气管网水力计算软件,采用的节点线性逼近法比平差法的方程阶数增多,收敛速度令人满意,计算结果具有较高的经济性。The hydraulic calculation in the design of urban gas pipeline network is a very important work. The traditional calculation method used before, for example, the integral square error, has disadvantages , such as long period,larger error and conservative. A new hydraulic calculation software for urban gas pipeline network is developed with Visual Basic 5. 0,in which the lineal shrinkage at juncture is adopted. Some calculation cases are given. The calculation speed is greatly improved with a high accuracy and satisfactory results.
