Abstract：Based on the developed drainage segment lining-surrounding rock flow system，water pressure distribution law behind prefabricated drainage segment lining of a high water pressure tunnel is studied by employing indoor test as research methods. Discussion focus on water pressure distribution law behind the segment lining for different drainage schemes such as limiting discharge only，blocking groundwater-limiting discharge is conducted. Meanwhile，an attempted analysis for the effect of discharge capacity，grouting circle and discharge outlet density on water pressure behind the lining is carried out，so as to reveal the conic relationships of external water pressure discount coefficient or external water pressure and flow discharge for the whole lining and different parts of the lining. The study results can provide a reference for the design of high water pressure tunnel lining.
