Three-dimensional calculation and analysis method for influence of buttresses on interval tunnels and station structures

Abstract

The invention relates to the technical field of building construction, in particular to a three-dimensional calculation and analysis method for influence of buttresses on an interval tunnel and a station structure. The method comprises the following steps: synchronously implementing a co-construction part of an underpass, an overpass bridge and a station and the station, installing beam pieces, and arranging the buttresses below the beam pieces for fixing; enabling the buttresses to be aligned with station columns within the range of the station, and detecting the maximum stress of a tunnel vault and an upper-layer bottom plate and comparing the maximum stress with the maximum load of the station. The invention discloses a three-dimensional calculation and analysis method for influence ofbuttresses on an interval tunnel and a station structure. The maximum stress of the vault and the upper-layer bottom plate of the tunnel is detected through the alignment of buttresses and station columns within the station range and compared with the maximum load of the station, then whether the stress borne by the vault and the upper-layer bottom plate is within the maximum load of the station or not is determined, and the stability of the tunnel structure is determined.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a three-dimensional calculation and analysis method for the influence of buttresses on section tunnels and station structures. Background technique [0002] At present, China's railway construction is in a golden period, and a large number of passenger dedicated lines and intercity railways have started and put into use one after another. [0003] In the current road and bridge construction, the joint construction of the upper span bridge and the rail station is implemented simultaneously with the station, and the rail station cannot bear the load of the upper bridge. Contents of the invention [0004] The purpose of the present invention is to provide a three-dimensional calculation and analysis method for the influence of buttresses on section tunnels and station structures, and to solve the technical problem that the existing rail stations cannot bear the load ...
