【摘要】 寿命预测是结构耐久性研究的一个重点。文章提出了以裂缝限值和承载力分别作为衡量隧道结构寿命终结标准,并分别对不同准则下结构寿命进行预测,通过比较确定衬砌结构最终寿命的方法。最后某海底隧道预测实例表明,该方法结果合理,可以作为同类研究借鉴。更多还原

【Abstract】 Service-life prediction of the structures may be one of the focuses in durability study field.In this paper,different criteria including cover crack limitation and bearing capacity are put forward to measure the life-span terminal of structures.Based on these standards,different life-span results can be obtained.Then the smaller of them could be considered as the durability of the structure. Furthermore,a prediction of service life for subsea tunnel is given as an example to explain this method.From the example,a conclusion can be drawn that this method is feasible and can serve as the reference in similar study.更多还原
