建国以来,我国铁路隧道衬砌结构的设计,主要是采用普氏理论和拉-布氏衬砌计算方法。大量的工程实践和科学试验证明,按照这一理论和方法设计的隧道衬砌,其受力情况和实际衬砌受力状态出入很大。因此隧道衬砌外荷的确定和计算方法是一个很值得研究的问题。
Since the founding of the People’s Republic of China, the design of the railway tunnel lining structure in our country mainly adopts the Platts theory and the La-Brinell lining calculation method. A large number of engineering practice and scientific experiments have proved that the tunnel lining designed according to this theory and method has a large discrepancy between the stress conditions and actual lining stress conditions. Therefore, the determination of tunnel lining load and calculation method is a very worthy of study.
