Abstract:
In order to understand the long-term strength attenuation and material ageing of tunnel structures, the author presented an explorative study on the durability design and service life prediction of the under-river tunnel lining segments constructed by shield driving method. The main topics under discussion here were: corrosion mechanism of RC segment lining structures, main factors affecting the durability of RC tunnel structures, durability of bolts connected segment joints and water-proofing materials, durability design method for segment linings, prediction of the service life on tunnel structures and the comprehensive prevention and cure measures which were intended to improve the durability of tunnel segment lining structures in engineering aspects. The results obtained here have been preliminarily used in Chongming Yangtze River Tunnel engineering project.
