摘要
隧道衬砌在浅埋段的结构荷载计算表明,复合式衬砌中的初期支护和二次衬砌一般要共同承担荷载。本文通过引用有限元分析中的接触单元来计算复合式衬砌在偏压荷载作用下,初期支护和二次衬砌之间的相互作用情况,以及它们各自的受力状况。
The calculation of structural load on the lining of tunnel with shallow overburden shows that the load on composite lining will be shared by primary support and secondary lining. In this paper, contact clement of Finite Element Analysis Method is taken for calculation of the interaction between primary support and secondary lining of composite lining and their bearing force conditions under the action of unsymmctri-cal load.
