Abstract According to the failure features of concrete lining under seepage load，a three-dimensional numerical coupling analysis of seepage field and stress field is made on the fracture regulation of underground concrete branch pipe lining. Based on cracking characters of concrete lining，the computing formulae of crack width and reinforcement rate for concrete lining under seepage load are given. Through compution to practical engineering, the infection of seepage induced by high pressure water inside pipe is demonstrated. An efficient computation method is provided for the design of underground concrete branch pipe with high pressure water.

Key words： underground concrete branch pipe coupling of seepage and stress field crack width lining reinforcement rate
