Abstract

The invention relates to a tunnel excavation three-dimensional model experiment loading device. The device comprises a loading frame, a front baffle, a rear baffle and self-balancing reaction frames, wherein the loading frame comprises frame columns, a moving cross beam and an upper cross beam; a plurality of lateral hydraulic cylinders are symmetrically installed on the inner sides of the frame columns; a plurality of vertical hydraulic cylinders are installed at the bottom of the moving cross beam; a lifting device is installed on the upper cross beam; the front baffle comprises a transparent organic glass baffle and a steel channel baffle; a hole is cut in the organic glass baffle; the organic glass baffle is arranged on the inner side of the steel channel baffle; more than one self-balancing reaction frame is arranged outside each of the front and rear baffles respectively; a plurality of jacks are arranged between the self-balancing reaction frames and the front baffle; and jack base plates are arranged on the front baffle. The device can generate various rock and soil mass three-dimensional stress fields with different burial depths and geological conditions and can achieve the chamber excavation model experiments under complicated conditions, such as different clear distances, different sections, and the like under high and low unsymmetrical pressure conditions.

Description

technical field

[0001] The invention belongs to the field of railway and highway tunnels, and in particular relates to a loading device for a tunnel excavation three-dimensional model experiment. Background technique

[0002] With the rapid development of infrastructure construction such as railways and highways, more and more railways and highways need to pass through mountains and rivers and lakes in the form of tunnels. Due to the constraints of various construction sites, various types of tunnels have emerged. Tunnels, such as small-diameter tunnels, double-arch tunnels, and cross tunnels, etc., and due to various geological conditions, the working environment of the tunnels also has different changes, such as large and small bias tunnels, etc. What should be used under different conditions? Such excavation method has attracted the attention of the engineering community. Different tunnel excavation methods will not only directly affect the stability of the tunnel surrou...
