Shield tunnel structure calculation system

Abstract

The invention provides a shield tunnel structure calculation system, which comprises a database module used for providing a segment model and a joint model; a segment determination module used for selecting a specified segment model from the database module; a joint determination module used for selecting a specified joint model from the database module; a segment joint assembling and combining module used for performing position combination on the specified segment model and the specified joint model and establishing a local column coordinate system to obtain a tunnel model; a load determination module used for determining a load according to the burial depth of the tunnel, decomposing the load by utilizing a local cylindrical coordinate system and applying the decomposed load to the tunnel model; a calculation and solving module used for generating a calculation file according to the tunnel model to which the load is applied and solving the calculation file; and an output module usedfor outputting the internal force of the specified section of the tunnel model obtained by the calculation and solving module. According to the invention, the segment and joint model can be downloaded from the database, thereby avoiding the tedious manual modeling, and improving the convenience.

Description

technical field [0001] The present disclosure relates to the field of shield tunnel structure design, in particular to a shield tunnel structure calculation system. Background technique [0002] At present, the calculation methods of the shield tunnel structure are divided into stratum-structure method and load-structure method according to the load consideration method. Compared with the stratum-structure method, the load-structure method has better calculation convergence, safer calculation results and easier programming The characteristics of simplification are widely used in the design of tunnel structures. [0003] However, there are still some defects when using the traditional load-structure method to calculate the shield tunnel structure. For example, the traditional load-structure method requires manual modeling, which is cumbersome to implement, and the contact surface and binding surface need to be defined manually, which is easy to cause confusion in the relatio...

[0003] However, there are still some defects when using the traditional load-structure method to calculate the shield tunnel structure

For example, the traditional load-structure method requires manual modeling, which is cumbersome to implement, and the contact action surface and binding action surface need to be defined manually, which is easy to cause confusion in the action relationship due to artificial definition errors
