Experimental Study on Flexural Resistance of Concrete Layer Attached to the Outer Wall of Slurry Retaining Wall
In order to ensure the construction safety and reinforcement effect during the process of treating and treating the damaged slurry retaining wall,the reinforcement measures of reinforced concrete attached to the damaged slurry retaining wall are put forward.Five groups of flexural tests were designed for the reinforcement model(1 group with no outer layer and 4 groups with different thickness of outer layer),and the strengthening effect and mechanism of outer layer on slurry retaining wall were investigated.The test results show that the failure mode changes from brittle failure to ductile failure after the addition of 5～20 cm thick outer layer,the bearing capacity and bending stiffness are significantly increased,the cracking moment is increased by 1.25～5.67 times,and the ultimate bending moment is increased by 2.75～13 times.
