摘　　要：高速铁路是我国关键性基础设施和重大民生工程,在我国经济社会发展中起着至关重要的作用,为实现国家长远发展担负着极其重要的责任。随着近年来我国铁路建设高速发展,隧道工程规模和数量突飞猛增,但高速铁路建设过程中隧道二衬混凝土裂缝问题不断凸显,给工程质量带来较大危害,同时也给列车运营安全造成了极大的威胁。因此,对富水黄土等特殊地质条件下高速铁路隧道二衬混凝土裂缝产生的原因进行全面分析并对质量缺陷整治关键技术进行研究显得十分必要,并具有显著的实践意义和探索价值。High-speed railway is a key infrastructure and a major livelihood project in our country.It plays a vital role in our country’s economic and social development,and shoulders extremely important responsibilities for the long-term development of the country.With the rapid development of railway construction in our country in recent years,the scale and number of tunnel projects have increased rapidly.However,the problem of concrete cracks in the second lining of the tunnel during the construction of high-speed railways has been continuously highlighted,which has brought greater harm to the quality of the project,and also poses a threat to the operation safety of the trains.Therefore,it is necessary to conduct a comprehensive analysis on the causes of the cracks in the secondary lining concrete of high-speed railway tunnels under special geological conditions such as water-rich loess,and to study the key technologies of quality defect remediation,which has significant practical significance and exploratory value.
