Abstract

The invention relates to the technical field of annular loading devices, in particular to a noose type non-uniform annular loading device and a using method thereof. The device comprises a shell, a tension mechanism, a force application point fixing mechanism and a data detection and acquisition mechanism, the shell is connected with the force application point fixing mechanism, and the force application point fixing mechanism is connected with the tension mechanism; the tension mechanism is connected with the data detection and acquisition mechanism, and the data detection and acquisition mechanism is used for setting the tension of the tension mechanism and acquiring the deformation of an experimental sample; an experimental sample is arranged on the inner side of the force application point fixing mechanism, the force application point fixing mechanism is used for fixing the position of the tension mechanism, the force application point fixing mechanism is pulled through the tension mechanism, and then pressure is applied to the experimental sample. The device has the advantages of non-uniform loading, controllable load distribution, non-unique load size, better conformity with the actual stress condition, low requirement on the strength of the outer wall and the like.

Description

technical field [0001] The invention relates to the technical field of hoop loading devices, in particular to a noose-type non-uniform hoop loading device and a usage method thereof. Background technique [0002] The external load applied by the ordinary hoop loading test device when testing the ultimate bearing capacity of the experimental specimen is an axial uniform load, which is not consistent with the actual force in the project, and the traditional method of testing the strength of the shield segment The test object of the experimental instrument is a single segment, which cannot test the actual bearing capacity after being assembled into a ring. In actual engineering, because the tunnel lining has the characteristics of different buried depths, soft rock interlayers, complex geological conditions, and obvious distribution of soft and hard strata, the stress on each part of the shield segment is not equal, so it is urgently needed An experimental device capable of si...
