Experimental study on the ratio of similar materials of medium-weathered granite in coastal rock slopes
In order to study the dynamic response of rocky slope on the southeast coastal slope under earthquake action,a simulation test of similar material ratio of medium-weathered granite was first carried out.A similar material proportioning scheme,with iron powder and quartz sand as aggregates,cement,clay and water as regulating materials,and quick-setting agent as binder,was selected for the test.A five-factor,four-level orthogonal table was designed and the rock compression tests were carried out.The results show that clay quality mainly affects the elastic modulus of similar materials,and the elastic modulus of similar materials increases with the increase of clay quality.Iron powder quality has a significant contribution to the elastic modulus and cohesion of simi-lar materials.The effect of cement quality on similar materials is relatively stable.The most suitable shaking table test ratio(quality ratio)is iron powder:quartz sand∶cement∶clay∶quick-setting agent∶water=405∶800∶130∶16∶2.1∶140.The results obtained by orthogo-nal design with materials as factor variables can provide a good reference for the simulation of other shaking table test materials.
