Abstract

The invention discloses a suspension tunnel pipeline performance hybrid simulation test method and device. The method is used for analyzing and researching dynamic characteristics of a suspension tunnel pipe body under vehicle-fluid action. The method comprises the following specific steps: dividing an integral structure into a physical substructure and a numerical substructure; based on a finite element algorithm or related software, establishing a numerical simulation model for the numerical substructure; prefabricating and installing the physical substructure according to a full-scale model or a reduced scale model; through a control system, a data interaction system and a data acquisition system, completing loading control on the physical substructure by the calculation information of the numerical substructure, and updating a model of the numerical substructure by the measurement information of the physical substructure; and finally, extracting required information through visual interface monitoring. The method solves the problem that the pure numerical algorithm is difficult to simulate the dynamic characteristics of the suspension tunnel under the action of complex loads, and also reduces the cost of the test technology and the requirements of site equipment and the like.

Description

technical field [0001] The invention relates to the technical field of civil engineering structure simulation and test, in particular to a method and device for mixed simulation test of pipeline performance of a floating tunnel. Background technique [0002] Suspended tunnels are the research focus of traffic engineering in recent years and in the future. With the deepening of research, more and more factors are taken into account in the response analysis of structures. As an important part of the floating tunnel system, the tunnel pipe body is not only subjected to fluid action for a long time in the operating state, but also the pipe body is affected by the vehicle load, and the pipe body vibration will excite the parametric vibration of the anchor cable. Therefore, it is very necessary to study the performance of the pipe system under the action of fluid and vehicle. [0003] Because pure numerical algorithms are difficult to simulate complex suspended tunnel structure p...
