Large-scale fluid-solid coupling model test bench being capable of prefabricating fault and test method

Abstract

The invention relates to a large-scale fluid-solid coupling model test bench being capable of prefabricating fault and a test method. The test bench comprises a bench body, wherein each inner wall of the bench body is provided with a tempered glass lined impermeable layer, thereby forming a sealed space, a top of the sealed space is provided with a water inlet, a fault prefabricating module is arranged in the sealed space and comprises a template fixed frame, two sides of the template fixed frame are mounted with the tempered glass lined impermeable layer and are provided with at least a pair of module sliding rails with adjustable inclination angles at the same time, the module sliding rails are provided with the fault prefabricating module, fluid-solid coupling similar materials are paved in the sealed space and embedded with monitoring members which are connected with an information collecting and storing device, and the information collecting and storing device is connected with a real-time information display device. The test bench simulates fluid-solid coupling characteristics of tunnels crossing the faults, and thus obtains conclusions relatively according with actual situations and guarantees construction quality and safety.

Description

technical field [0001] The invention relates to a model test device, in particular to a large-scale fluid-solid coupling model test stand capable of prefabricating faults and a test method. Background technique [0002] With the development of my country's economy and science and technology, submarine tunnels crossing faults, cross-river tunnels, and deep-buried large-section tunnels in karst areas are becoming more and more common in transportation construction. The impact of water on the successful construction of these projects is also very significant. Many technical issues urgently need to be resolved. Many experts hope to realize the simulation of on-site working conditions through model tests, and draw conclusions to guide the safe and smooth progress of on-site construction. [0003] At present, although there are devices for fluid-solid coupling model tests, this type of equipment is mainly used to simulate the seepage field and stress field in the real situation on...
