Dynamic and static testing system and method for multifunctional wharf structure

Abstract

The invention discloses a dynamic and static testing system for a multifunctional wharf structure. The dynamic and static testing system comprises a detachable large-rigidity bearing frame, a vertical loading actuator, a horizontal loading actuator, a multi-channel controller, an electro-hydraulic servo oil source system, a data collecting system as well as a displacement and force sensor. The maximum clearance size of the loading frame is 4.5m* 4.5m*4.5m (L*W*H); a testing space can be randomly adjusted according to test sample requirements; a loading mode is that vertical and horizontal combined loading can be finished through two 10-100 t static vertical actuators and 3-20t dynamic horizontal actuators; integral or member stress performance tests of the high pile frame wharf structure with large water level difference under a combined effect of various complicated working conditions such as gantry crane load, piling load and ship load are simulated. The invention further provides a dynamic and static testing method for the wharf structure, which can be used for really simulating the stressed deformation performances of the wharf structure under various complicated stressed conditions and can be also used in stress experiments of similar structures.

Description

technical field [0001] The invention relates to a stress deformation test system and a test method suitable for space structural parts, in particular to a force deformation test system and a test method for a wharf space structure. Background technique [0002] With the development of the national economy, the infrastructure of inland shipping has also made great progress. However, due to the complex hydrological and geological environments faced by the construction of inland wharfs, under the influence of ship mooring force or impact force and various complex working conditions, it is extremely difficult It is easy to cause damage to the high-piled frame wharf with large water level difference. Therefore, in the construction of the high-piled frame wharf, the stress analysis of the overall structure of the wharf and the common use of piles, columns, beams, plates, walls, frames, nodes, etc. The structural performance test of components is particularly important, but in the ...

[0002] With the development of the national economy, the infrastructure of inland shipping has also made great progress. However, due to the complex hydrological and geological environments faced by the construction of inland wharfs, under the influence of ship mooring force or impact force and various complex working conditions, it is extremely difficult It is easy to cause damage to the high-piled frame wharf with large water level difference. Therefore, in the construction of the high-piled frame wharf, the stress analysis of the overall structure of the wharf and the common use of piles, columns, beams, plates, walls, frames, nodes, etc. The structural performance test of components is particularly important, but in the actual technology, there is no test system and test method that can simulate the overall structure or components of the wharf under the action of various complex working conditions. The large-scale structural test system is a method for testing structural mechanics Its research and development is of great significance to the design inspection, optimization and verification of the infrastructure that must be built in the process of national modernization.
