Based on the matrix laboratory platform,we take dredger delivery system’s computational simulation program into encapsulation process and establish dredger transportation analysis system (DTAS).Assembling some methods of dredge pump and pipeline’s characteristic firstly,including the pump and pipeline data file storage and query,dredge pump and pipeline data files’storage and query,calculation of dredge pump pipeline’s characteristic curve and the choice of a variety of calculation models,back-analysis of the construction date,and the characteristic calculation of relay pump,DTAS can calculate and analyze the dredger delivery system more systematically and comprehensively.The interface of DTAS system is simple,and provides a convenient calculation tool for the construction and technical personnel.
