Problems solved by technology

At present, the selection of tunnel boring machine type, cutter head configuration and construction parameters is generally based on the results of indoor rock mechanics tests, but the construction object of tunnel boring machine is rock mass, because the mechanical behavior of rock mass is affected by environmental factors (such as ground stress) and structural factors. Due to the influence of factors (such as rock mass structural plane), the mechanical test results of the rock cannot represent the mechanical behavior of the rock mass, and the equipment and construction parameters selected accordingly may not be able to exert the best efficiency of the tunnel boring machine

Abstract

The invention discloses a tunnel boring machine two-dimensional loading analog test device. A spherical pad used by the device is connected with a common cross beam of a pressure machine through bolts, two ends of the vertical loading tension transfer column of an installment axis type loading sensor are separately provided with the spherical pad and a cutter holder, cutters are fixed on the cutter holder though bolts, two left and right ends of a loading holder are separately provided with displacement sensors, the displacement sensors and axis type loading sensor are connected with a computer through a data sampling apparatus; a horizontal lifting jack is fixed with a left lateral plate through bolts, a horizontal loading tension transfer column is fixed on the left side of a right lateral plate, four draw bars are used to connect the right lateral plate and the left lateral plate, the piston ends of the horizontal loading tension transfer column and the horizontal lifting jack are separately provided with a test piece right bearing plate and a test piece left bearing plate; and a high speed CCD camera is mounted at the front of a test piece and is connected with a computer through a data line. The device has simple structure, convenient operation, low cost, rich test data, complete test result and high reliability and is easy to process.

Description

technical field [0001] The invention belongs to the technical field of rock mechanics tests, in particular to an experimental device for simulating the two-dimensional rock-breaking process of a tunnel boring machine (TBM), through which the rock-breaking mechanism of the tunnel boring machine can be studied, and it is the construction equipment and construction parameters for long tunnels. In addition, this device can also provide a new experimental method for the study of rock mass fracture. Background technique [0002] TBM is the English abbreviation of tunnel boring machine, which is a kind of tunnel boring machine specially for hard rock. The excavation process of the tunnel boring machine includes: the hob penetrates into the rock mass on the tunnel face through thrust, and the rotation of the cutterhead drives the hob on the cutterhead to crush the rock mass, so that the rock on the tunnel face is broken into fragments. Therefore, the tunnel boring machine has uniqu...
