Optimization Experimental Research on Asphalt Concrete Core Wall Mixture Ratio of Yatang Reservoir
This paper conducts an experiment study on the asphalt concrete core wall mixture ratio optimization of Yatang Reservoir through analysis of the mineral chemical components of the aggregate.It optimizes the mixture ration using the content of SiO_2 as the key measurement index,and tests the stability and freeze thawing cycle of the optimized mixture ratio.It also investigates the mechanical properties of bending,pushing,pressure,deformation and leakage of the asphalt concrete.The optimized mixture ratio is proved to achieve the expected results through practical implementation.As a result,the paper provides a new mixture ratio mode for asphalt concrete core wall.
This paper taking a district of Guiyang karst geological conditions for example,and expounds the development situation and the underground karst.And put forward the effective foundation treatment measures and building foundation type selection,hope to provide certain reference for future similar projects.
