Technical Field
The utility model relates to the technical field of geotechnical engineering, in particular to a dry-wet circulation test device for a rock mass structural surface.
Background
The structure has a controllable influence on the stability of the rock mass in engineering, in particular to a weak structure surface containing a weak interlayer. The weak structural surface is a weak band with a certain thickness in the rock mass, has the characteristics of high compression, low strength and the like compared with the rock mass at two adjacent sides, and generally controls the deformation and stability of the rock mass. The rock mass containing the weak interlayer can be subjected to the action of the dry-wet circulation of water flow for a long time due to the natural environment, and the weak structural surface is used as a weak part in the rock mass, so that the physical and mechanical properties of the rock mass can be deteriorated, and further geological disasters and engineering instability are caused. The effect of the wet and dry cycle on the rock mass, in particular on the weak structural face of the rock mass containing the weak sandwich layer, is therefore not negligible.
In recent years, there are some test devices for performing dry-wet cycle action on rock mass samples, for example, patent publication No. CN214503181U, and patent publication No. entitled test device for rock mass damage under the action of dry-wet cycle coupling confining pressure. However, most of the existing experimental objects are homogeneous rock masses, and the rock masses containing weak interlayers are rarely used as research objects, and the physical and mechanical properties of the weak structural surfaces of the rock masses under dynamic water pressure are rarely considered. In the test process, a limited number of samples are usually placed in a water storage container for saturation, and the problems of long sample saturation time, different saturation degree and the like exist, so that the efficiency is low. Therefore, how to realize the dry-wet circulation process of rock mass structural surface samples containing weak interlayers in batches is a theoretical and technical problem to be studied intensively in the geotechnical engineering field.
