| Abstract: | By the characteristic of hydraulic pressure tunnel＇ structure and load,it inquire into minimum overlay thickness of hydraulic pressure tunnel,big or little of principal stress,external water pressure,the design of breaking resistance and crack resistance for reinforced concrete lining,the design of spacing for expansion and contraction,width of circumferential crack propagation etc.It gives a model and method for consideration.It emphasizes unite acceptance for lining and adjoining rock in hydraulic pressure tunnel.It need filling grouting and consolidation grouting in hydraulic tunnels. |
