| This paper' s main content is the reuse of waste rock of Dabagou Tunnel. Firstly, the environment harm of the waste rock is studied; Secondly, we research the physics and mechanics property of the waste rock of the Dabagou Tunnel and get the physics and mechanics property index of waste rock; Thirdly, after comminuting the waste rock and compounding concrete as coarse aggregate, we make the comparison between it and the Songshan stone in the Fuxin building market at present, It proves to possess extension application value; Fourthly, on the foundation of it, we utilize waste rock as coarse aggregate to compound high strength concrete, steel fiber high strength concrete, polymer cement concrete, asphalt concrete by uniform design and research their mechanics property index by experiment. We get optimized equation and optimum mixing proportion of all kinds of waste rock concrete; Lastly, we advance to simulate and forecast the compression strength of waste rock high strength concrete and steel fiber high strength concrete by Neural network which establish the base for further studying. |
