Abstract

The invention relates to a composite rock mass conventional direct shear test sample manufacturing combined die device and a manufacturing method, the device comprises a shear box, a JRC steel template, a base template, a flat pressing plate, a counter-force frame and a pouring template, the square JRC steel template and the shear box are arranged above the base template, the base template is connected with the reaction frame through two fixing bolts which are symmetrically arranged, a pressurizing valve and a fixing jackscrew are arranged on the reaction frame, and a flat pressing plate which is arranged in a cavity of the shear box is arranged below the fixing jackscrew to form a pressurizing device. According to the combined mold device, the manufacturing convenience degree of composite samples with different cementing surfaces is enriched, and damage to the samples and uncertainty of interface distribution requirements caused by traditional on-site drilling and cutting sampling are avoided. One-time forming for manufacturing of a composite test block is realized. Meanwhile, compared with on-site sampling, manpower loss and time waste of sample manufacturing are greatly reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a combined mold for a composite rock mass sample, in particular to a combined mold device and a manufacturing method for making a conventional direct shear test sample of a composite rock mass. Background technique [0002] Layered composite rock formations, a special geological body, are widely distributed in nature. After long-term complex geological tectonic movements and weathering erosion, this kind of rock formations is often composed of rock layers of different lithologies alternately. Different from rock mass of single lithology, layered composite rock mass has the characteristics of heterogeneity, discontinuity and anisotropy, and its mechanical properties are not only affected by the mechanical properties of structural planes between layers, but also by the Mechanical properties, the inclination angle of the structural surface and other factors. Internal joints and cracks are obvious, and the combination between laye...
