近年来,我国黄土地区城市轨道交通系统发展迅猛,一系列黄土地区地铁隧道结构安全性评价相关问题日益凸显,亟待开展黄土地区地下隧道结构长期稳定性与安全性相关的问题研究。针对地铁长期运营振动引起的黄土地铁盾构隧道结构动力响应研究相对滞后的现实,特别是地铁列车振动荷载作用下盾构隧道结构的损伤特性和寿命预测研究严重不足的问题,总结了国内外重要研究成果,对地铁列车振动对黄土地区地铁盾构隧道结构影响的研究现状进行分析,主要包括地铁列车振动荷载研究列车振动荷载下黄土动力特性、隧道结构响应及隧道结构长期寿命研究等,分析了当前研究存在的问题,并进一步提出了解决问题的思路和想法。
In recent years, the rapid development of urban rail transit system in China’s loess area has highlighted the problems related to the structural safety evaluation of subway tunnels in the loess area. Research on the long-term stability and safety of underground tunnel structures in the loess area is urgently needed. In view of the fact that the study on the dynamic response of the loess subway shield tunnel caused by the long-term operation vibration caused by the subway is lagging behind, especially the damage characteristics and life prediction of the shield tunnel under the vibration load of the subway train, Research results, the impact of subway train vibration on metro shield tunnel structure in the loess area is analyzed, including the dynamic load of loess train under the vibration load of the train, the response of the tunnel structure and the long-term life of the tunnel structure, and so on The current study of the problems, and further proposed ideas and ideas to solve the problem.
