Abstract

Belonging to the technical field of machinery, the invention relates to an electromagnetic slope loading test device and a loading method. An electromagnetic force loading apparatus is placed in the cavity of an outer shell, a slope model box is placed in the cavity of the electromagnetic force loading apparatus, a horizontal clamping apparatus is placed in the cavity of the slope model box, an inner threaded hole is located at the center of the slope model box's front panel, a horizontal clamping bolt is connected to the inner threaded hole through a thread and passes through the inner threaded hole, the thread end of the horizontal clamping bolt and the inner threaded hole of a connection block are in fixed connection. A clamping plate is connected to the cavity of the slope model box, the connection block is located between the front panel and the clamping plate, the right panel of the slope model box is connected to the front panel through a first hinge and a second hinge. And theright panel of the slope model box and a rear panel are connected together through a first fixed bolt. The electromagnetic slope loading test device provided by the invention has the characteristics of simple structure and convenient use, and can accurately simulate the stability condition of slope under the action of self weight or other external load.

Description

technical field [0001] The invention relates to an electromagnetic slope loading test device and a loading method, which belong to the technical field of machinery. Background technique [0002] Under the action of self-weight or other external loads, landslides often occur on slopes, which pose a serious threat to national property and people's lives. With the vigorous development of infrastructure in our country, a large number of slope stability problems are involved in mines, water conservancy and transportation. Therefore, it is very necessary to study the stability of slopes under the action of self-weight or other external loads. At present, the slope model test uses the bearing plate to load, but there are phenomena such as uneven loading and stress concentration, so there are still shortcomings in simulating the gravity field. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an electromagne...
