建立了基于裂缝限值准则的越江隧道衬砌结构服役寿命预测的方法体系,利用所建立的方法对上海长江隧道衬砌结构的服役寿命进行了理论预测,结果表明该隧道可以满足100年的设计使用年限。研究成果已在上海长江隧道中得到了初步应用。
The method system of fiver-crossing ttmnel lining structures service life predication based on crack limit has been established, Then the method was applied to Shanghai Yangtze River Tunnel segment lining structures service life prediction, the result shows that it can meet 100 years design service life. The resuits obtained here have been preliminarily used in Shanghai Yangtze River tunnel project.
