Embodiment 1

[0043] as attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 Shown in this embodiment is a model test system for the interaction between the tunnel and the anti-sliding support structure in the landslide. The tunnel structure 2 is arranged inside the landslide structure 1. When the tunnel structure 2 is arranged on the landslide structure 1, according to the tunnel structure 2 The position relationship between the axis and the axis of the landslide structure 1 is provided with an anti-sliding retaining structure 3, so that when the simulated load loading system is applied to the landslide structure 1, the anti-sliding retaining structure 3 can reduce the force or force of the movement of the landslide structure 1 on the tunnel structure 2 When the tunnel structure 2 is reinforced and the landslide structure 2 is moved, firstly, the theoretical force analysis is carried out on the key areas of the tunnel structure 2 and the...

Embodiment 2

[0049] as attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 Shown in this embodiment is a simulation test method for the interaction between the tunnel and the anti-sliding retaining structure in the landslide, the tunnel structure 2 and the anti-sliding retaining structure 3 are prefabricated according to the scale of the model, and the mode of simulated load loading is selected; When the axis of the tunnel structure 2 is set parallel to the axis of the sliding bed 1c, a force is applied to the sliding body 1a through the simulated load loading system, so that the sliding body 1a moves to generate a shear force on the vault position 7 of the tunnel structure 1, and the anti-sliding support The retaining structure 3 is connected to the tunnel structure 2, and has the function of reinforcing the tunnel structure 2. The test elements 4 are densely arranged on the vault position 7 of the tunnel structure 2, which can realize...

Abstract

The invention relates to the technical field of geotechnical engineering landslide model test and monitoring, and in particular relates to a model test system and method for interaction of a tunnel and an anti-slide retaining structure in landslide. The test system comprises a landslide structure, a tunnel structure, an anti-slide retaining structure, a simulation load loading system and test elements; the tunnel structure is arranged in the landslide structure, and the anti-slide retaining structure is arranged on the landslide structure and used for reducing the acting force generated by movement of the landslide structure on the tunnel structure or reinforcing the tunnel structure; the simulation load loading system is arranged on the landslide structure and is used for simulating the application of acting force to the landslide structure; the test elements are respectively arranged on the landslide structure, the tunnel structure and the anti-slide retaining structure; the system is used for monitoring stress and deformation of the tunnel structure and the anti-slide retaining structure, and the problems that only the internal force and displacement deformation characteristicsof the integrity of the tunnel structure are monitored in the prior art, and monitoring of key areas where diseases possibly occur in a tunnel is lacked are solved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering landslide model tests and monitoring, in particular to a model test system and method for the interaction between tunnels and anti-slide support structures in landslides. Background technique [0002] When building roads or railways in areas with complex geology, tunnels need to be excavated to cross the mountain. Generally speaking, the geology of the difficult and dangerous mountainous areas in Southwest China is complex and changeable, and geological disasters such as landslides are widely distributed, which brings huge impacts on the safety of the tunnel structure itself and the safety of line operation. Most of the existing studies focus on the qualitative analysis of the design parameters of the anti-sliding retaining structure and the stability of the landslide body on the deformation control effect of the tunnel structure. The lack of quantitative analysis of this problem m...
