Abstract

The invention discloses a device and a method for measuring the contact area of a natural loess joint. The device comprises a sealed barrel, an air inlet device, a porous sample placement platform and a barrel cover, wherein the barrel cover is arranged at the upper end of the sealed barrel; the porous sample placement platform is vertical to the inner wall of the sealed barrel and is arranged under the barrel cover; an air inlet is formed in the bottom of the side wall of the sealed barrel, and the air inlet device is connected with the air inlet; an air outlet is formed in the barrel cover. The device provided by the invention can enable powder to be evenly distributed on the surface of a joint; the system is convenient in processing, materials are easy to obtain, and the system has better economic benefit; the operating principle of the system is easy to understand, the operation of the system is simple, and a better even spreading effect is achieved.

Description

technical field [0001] The invention belongs to the field of measuring natural loess joint parameters, and in particular relates to a measuring device and method for the contact area of ​​natural loess joints. Background technique [0002] Loess joints are gaps formed by internal and external stresses and new structures after the formation of loess, which widely exist in the Loess Plateau region, and its existence has a non-negligible impact on the characteristics of loess. Joint seepage is an important factor affecting the stability of tunnels, caves, mountains, and road slopes in loess areas. Joint contact area is an important factor affecting joint seepage. Therefore, a simple, economical and practical method is explored to obtain joint contact area with high practical significance and engineering value. [0003] At present, the contact area of ​​natural joints is obtained by combining two pieces of joint surface morphology processed by computer, which requires high tech...
