Therefore, to address the aforementioned two problems, a joint element and a coupling method for simulating the hydromechanical interaction of the reinforced concrete lining are adopted, which consider the effects of the joint load-bearing characteristics of the steel lining and the consolidation layer and the internal water exosmosis on the stability of the steel lining at the collapse zone.
When suffered from waterlogging, membrane of plant cells was damaged, causing the exosmosis of cytoplasm and consequent increasing of conductivity.
