[0057] 1.1 Research content
[0058] 1) Research on the dynamic response characteristics of prefabricated comprehensive pipe gallery in soft soil foundation under traffic load
[0059] Based on the large-scale model test, the dynamic response characteristics of the dynamic interaction system of the typical structure of the prefabricated integrated pipe gallery under the action of traffic load are studied, from the properties of the soil layer, the vehicle load, the vehicle dynamic load coefficient, the distance from the pipe gallery to the lane, and the covering soil of the pipe gallery. In terms of burial depth, etc., analyze the longitudinal and lateral force, deformation characteristics and change laws of typical prefabricated pipe gallery structures when relevant parameters change, explore its response mechanism, and establish the dynamic response characteristics of prefabricated comprehensive pipe gallery in soft soil foundation under traffic load Analytical models and th...

Description
technical field [0001] The invention belongs to the technical field of building evaluation, and in particular relates to a method for measuring the coupling of nonlinear dynamics and environmental media of a utility gallery under traffic loads. Background technique [0002] At present: With the development of urbanization, the construction of urban underground utility tunnels and its management technology are becoming more and more perfect, but the current research on the design and construction technology of urban comprehensive utility corridors is still not systematic, with few achievements, and is still in the process of exploration and gaining experience. There are still some problems in the construction of underground comprehensive pipe gallery, which restrict its rapid development. The standardization and modularization of underground utility corridors is an important prerequisite for the promotion of prefabricated assembly technology for underground utility corridors...
