Abstract：
Taking the header inside inspection well and the circuit as the research object, analyses the influence of the number of parallel end drilling, drilling depth and drilling spacing on the hydraulic characteristics of the pipe network system. With the established hydraulic model and Matlab software, calculates the resistance loss of buried pipe system under the conditions of different design schemes. Analyses the hydraulic characteristics of different types of buried pipe network, and provides the optimization design method for the buried pipe system.
