Title:
SEAWATER AGING IMMERSED TUNNEL GINA WATER STOP TIME-VARYING CONSTITUTIVE MODEL CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/201522
Kind Code:
A1
Abstract:
A seawater aging immersed tunnel GINA water stop time-varying constitutive model construction method, comprising the steps of: obtaining stress relaxation curves at different aging temperatures; determining an aging performance change value P of rubber used by a GINA water stop; determining a stress-strain relationship curve of the GINA water stop; obtaining a stress-strain relationship curve of a full aging period; and constructing a constitutive model of GINA water stop stress relaxation and seawater aging. The method can achieve dynamic monitoring on the service state of a GINA water stop, providing a basis for service life evaluation and risk early warning of the GINA water stop.
