随着近年来社会经济的飞速发展,我国的高速铁路也得到了迅速的发展。高速铁路线上的控制性工程是隧道工程,隧道工程的结构安全对列车司乘人员和列车运行安全问题有着十分重要的作用。而影响隧道工程结构因素的首要危害就是隧道衬砌裂缝,为了保证工程质量和行车等人员安全,必须对衬砌裂缝产生的原因和治理的措施等进行研究分析。研究人员根据近年来的一些工程作出了以下几点分析:第一,以某一条双线隧道作为对象,在荷载结构法的基础上作出衬砌结构的空间模型,分析在常见质量威胁下。如偏压、衬砌背后空洞和衬砌厚度达不到等情况,隧道衬砌变形以及裂缝的分布状况。
With the rapid social and economic development in recent years, the high-speed railway in our country has also been rapidly developed. The control project on the high-speed railway line is a tunnel project. The structural safety of the tunnel project plays a very important role in the safety of the train division by crew and trains. The main hazard that affects the structural factors of tunnel engineering is the tunnel lining cracks. In order to ensure the project quality and the safety of driving and other personnel, it is necessary to conduct research and analysis on the causes of the lining cracks and the treatment measures. Based on some projects in recent years, the researchers made the following analysis: First, taking a double-track tunnel as an object, a space model of the lining structure was made on the basis of the load structure method, and the analysis was under common quality threats. Such as bias, lining behind the lining and lining thickness of less than the case, the tunnel lining deformation and the distribution of cracks.
