In aspects of often used reduction coefficient of lining external water pressure in tunnel water inflow estimation and hydrotechnical tunnel,this paper analyzes lining external water pressure calculation of rich water segment of tunnel under "limited drainage" via simplified model,and discusses the implementation of "limited drainage" so to conclude some useful conclusions for design reference.
