天津海河隧道抗震研究概述
|
摘要
天津地处华北地震区的华北平原地震带上,中央大道海河隧道是抗震重点工程。该文介绍了海河隧道的工程地质概况,在此基础上,上海交通大学提出了用大型有限元三维仿真模拟和经典的等效质点-弹簧模型两种方法进行抗震分析,并首次提出了"SSUM(Sophisticated and Simple Unified Method)"抗震分析方法,对今后类似工程有重要的借鉴作用。
TTianjin is located on the North China Plain seismic belt of the North China seismic area.The Haihe Tunnel of the Central Avenue is the key seismic work.The article introduces the engineering geology of Haihe Tunnel.On this basis,Shanghai Jiaotong University puts forward the use of the large finite element 3D simulation and the classical equivalent mass-spring model to carry out the seismic analysis,and firstly proposes the seismic analysis method of SSUM(Sophisticated and Simple Unified Method) to be referred for the similar projects in the future.
