| 摘 要： | 推导了隧道管段由温差变化引起的应力计算方法，根据施工顺序，分为底板浇筑阶段、侧墙与顶板板筑阶段、连续成整体阶段、浮运与沉放阶段、运营阶段等5个阶段，分别计算混凝土管段内的拉应力。计算结果表明，管段侧墙内存在较大的拉应力，需要采取合理的措施，以防止裂缝的发展。

| Abstract: | When the deformation is constrained,the cracks will develop in immersed tunnel.Calculation method of thermal stress is proposed.Based on the method,the construction of immersed tunnel is divided into five phases:placing floor,placing wall and deck,linking units,floating and immersing,and application,then the stresses of concrete tube segments are calculated reapectively.The results show that there is great stress in outer wall,and measures must be taken to control cracks. |
