Theoretical Calculation and Test of Mechanical Properties of Mobile Flood Protection Wall

Abstract

Abstract With global climate change, a growing number of countries and regions will have large flood disasters. Therefore, an effective and environmental protection waterproof system is essential. The mobile flood protection wall not only has the flood control capacity comparable to the traditional flood control system but also has a better landscape effect that can meet the needs of residents. However, the mobile flood protection wall presently lacks the basis of practical application and theoretical calculation. Therefore, this paper provides a theoretical calculation method for strains and stresses on a mobile flood protection wall and carries out a real test to verify the reliability of the theoretical calculation. A test pool was built to obtain the data of the strain of the mobile flood protection experiments and reflections on the risk wall during the impoundment process by strain gauge and data acquisition instrument. Through the theoretical calculation method provided in this paper, the actual test conditions are calculated, and the results obtained in the test are mutually validated. The test validates that the mobile flood protection wall is reliable in practical engineering, and the proposed calculation method can be applied to the mobile flood protection wall.
