- Abstract:
- Based on the statistical analysis of water pressure load on tunnel lining,the main influencing factorsof water pressure are analyzed. The main control ingredients are geological structure,rock permeability,thesupply and drainage of Karst water,vertical zonation of Karst water. The population distribution characteristicsof water pressure on liner are also studied with different drainaged designs. A large number of drainage leadsto a small water pressure on lining. When full-sealing water proofing lining is employed,the water pressure onlining is equal to hydrostatic pressure. When Karst water is released,the water pressure can be reduced sharp-ly. The water pressure on lining can be weakened by controlled drainage design.Based on the statistics of datameasured in field,a fuzzy synthetic evaluation system of water pressure is established. According to the evalu-ation results of water pressure,reasonable choice of different drainage patterns can be acquired.
