As a deceleration and siltation remediation buildings,in recent years permeable framework has been gradually promoted in the waterway regulation engineering and mostly widely used in the guardian projects.A new type of permeable framework,i.e.twisted double H permeable framework was developed and it was tested in the bottom protection of Tongzhousha submerged breakwater in first phase deep channel construction,12.5 m below in Nanjing.The current waterway regulation engineering quality inspection standards does not make the specific provisions,which is the guarantee of the protective effect.By flume tests,this paper proposes the test standard of the permeable framework for the bottom protection.And on this basis,the appropriate test methods are proposed using the measured scan sonar image analysis.The indoor optical image test verified well.
