Design analysis method for tunnel steel frame connection longitudinal beam
TLDR
In this article, a design analysis method for a tunnel steel frame connection longitudinal beam is presented, where the foundation load of each arch spring of the steel frame, the settling volume of each ar spring and the internal force of each section of the connection longitudinal beams during different working conditions under a connection longitudinalbeam timbering function.Abstract:
The invention relates to the field of the tunnel engineering, and particularly relates to a design analysis method for a tunnel steel frame connection longitudinal beam. According to the mechanism of action of the steel frame connection longitudinal beam, a mechanical analysis model of the connection longitudinal beam is established, and a force method is used for solving to obtain the foundation load of each arch spring of the steel frame, the settling volume of each arch spring and the internal force of each section of the connection longitudinal beam during different working conditions under a connection longitudinal beam timbering function. Tunnel design personnel can utilize the obtained foundation load of each arch spring of the steel frame, settling volume of each arch spring and internal force of each section of the connection longitudinal beam to carry out checking calculation on the foundation bearing capacity of each arch spring of the steel frame, the settling volume of each arch spring and the strength of the connection longitudinal beam under different working conditions, and finally, the design of the connection longitudinal beam is finished. By use of the design analysis method for the tunnel steel frame connection longitudinal beam, a theoretical basis can be provided for the design of the connection longitudinal beam, and a situation that blindness is in the presence since the design and the application of the connection longitudinal beam only depend on experiences at present can be avoided.read more
