Description
Technical Field
The invention relates to the field of tunnel engineering, in particular to a large-scale tunnel vibration table test, and specifically relates to an integral shearing variable flexible boundary power model box for a cross-fault tunnel.
Background
Since the occurrence of earthquake of Osaka and Wenchuan, a large amount of underground structures are damaged, and the earthquake damage of tunnel engineering is obvious. The fact that the tunnel is seriously damaged enables scientific researchers to realize the clear consciousness, and the progress and the development of the earthquake-resistant analysis and evaluation theory of underground engineering are particularly important to promote.
At present, the research means of the tunnel seismic response problem mainly comprises four types of field investigation, theoretical analysis, numerical simulation and model test. Among them, the model test based on the vibration table can intuitively and truly reflect the seismic response of the rock-soil mass and the tunnel lining structure, and thus is widely adopted.
The dynamic model box is the necessary equipment for the vibration table test. The existing vibrating table model boxes generally comprise three types, namely a rigid model box, a cylindrical flexible model box and a layered shearing model box. When the rigid model box is tested, the rigid model box cannot be sheared and deformed along with a soil body, so that the difference between the test and the actual situation is large. The layers of the layered shearing model box can freely slide, and the shearing deformation of the soil body in the vibration process can be simulated, but because the layered framework of the layered shearing model box is a whole, the situation that stratum parameters such as a soft and hard interface, a cross-fault tunnel and the like have changes along the axial direction of the tunnel is difficult to simulate. Cylindrical flexible models are also difficult to model the boundaries in the presence of two different strata.
Therefore, a novel power model box is urgently needed to be designed at present, so that the dynamic response of the cross-fault tunnel at the non-active fault interface under the action of an earthquake is well simulated.
