Mechanical Characteristic Research of Novel Prestressed Double Composite Linings

Abstract:

It is wildly attentive but controversial, in the area of structure engineering, how to assess and analyze the mechanical behavior of independent load-bearing or the joint load-bearing for double composite linings structure. The present paper is aim to discuss its working mechanism. The mechanical behavior of novel prestressed double composite linings is analyzed by using 3-D non-linear finite element method, comparing with the 1:1 simulation test. The numerical values are close to the test values including the deformation, the stress, and the opening of the gap between the inner and outer linings. The results show that the steel bars are most important component for joint load-bearing of the double linings and the cushion between the inner linings and outer linings can satisfy the independent load-bearing requirement. The numerical values are quite agreement with those of the test, which verify the mechanical behavior and working mechanism of the prestressed double composite linings. This research can help to the design of similar engineering projects.
