Abstract

The invention discloses an earthen site rammed soil-site body interface force mechanism test device and a using method thereof. A sample prepared by a sample preparation device is divided into two layers: a pull-up piece and a pull-down piece, and a rammed soil-site body interface is formed between the layers. The surface of the sample is shaved. The occlusal force of the earthen site rammed soil-site body interface is enhanced, a shearing test is carried out on a strain control type direct shear apparatus through the sample, and the adhesion force and a friction angle of the site rammed soil-site body interface are obtained from a test result; a universal joint is mounted on the pull-up piece of the sample, a tensile strength test is carried out on a universal testing machine, the torsionis removed, and the tensile strength of the site rammed soil-site body interface is obtained. The method is simple in operation, convenient in application, low in manufacturing cost and capable of effectively measuring the maximum tensile strength of the interface of the sample.

Description

technical field [0001] The invention belongs to the technical field of research on the mechanical properties of the rammed soil-site body interface in the protection and reinforcement of earthen ruins, and specifically refers to a test device for the force mechanism of the rammed soil-site body interface of the earthen site and a use method thereof. Background technique [0002] my country is one of the ancient civilizations in the world. Its long history and splendid culture have long been recorded in the history of human civilization in the world. The historical process contained in Chinese earthen sites stretches from the Stone Age to modern times, and they are important cultural relics resources for human beings. Earthen ruins are distributed all over the country. As of the sixth batch of national key cultural relics protection units, there are about 400 earthen sites of national key cultural relics protection units that have been announced, distributed in 30 province...
