摘　　要：对广贺高速公路某偏压大跨度小净距隧道施工进行数值模拟计算,得出隧道变形、应力随施工工序的变化规律,提出在施工中的注意事项,对同类工程的安全施工提供理论依据。By numerical simulation and calculation for the construction of a bias large-span small-clearance tunnel in Guangzhou-Hezhou Expressway,this paper obtains the regularity of deformation and stress of tunnel changing with the sequence of construction and proposes the precautions during construction so as to provide the theoretical basis for safe construction of the similar projects.

关 键 词：偏压隧道 大跨度隧道 有限元模拟 变化规律
