摘要:

为了研究盾构法隧道管片衬砌结构强度的历时老化和衰减及其服务寿命的预测问题,提出了对其进行耐久性设计的一种基本方法。主要讨论的内容有:钢筋混凝土管片结构的腐蚀机理; 影响隧道混凝土结构耐久性的主要因素; 管片接头螺栓和防水材料的耐久性; 钢筋混凝土管片结构耐久性设计方法; 隧道结构服务寿命预测,以及提高隧道管片衬砌耐久性的工程措施——综合防治。该研究成果已在崇明长江隧道工程中得到了初步应用。

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.
