The constant mi in the Hoek-Brown (H-B) criterion is a fundamental parameter required for determining compressive strength of rock. In this paper, drilling parameters provide new basis mi. An analytical relationship between and established consideration contact response bit cut rock crushed zone. New models are developed to predict triaxial (TCS), internal friction angle φ cohesion c Drilling tests carried out on 6 types study correlation A comparison predicted values mechanical properties...
Currently, the unified strength criterion (USC), three-dimensional Hoek-Brown (3D H-B) and generalized theory (GUST) are three types of typical rock criteria. In this paper, a comparative study criteria is performed for rocks. Based on nonlinear characteristics meridian deviatoric planes, USC can predict under triaxial stress state. The composed two failure functions planes. surface in principal space satisfies smoothness convexity. predicted five true tests were compared among USC, GUST, 3D...
Field evaluation of the strength properties jointed rock masses is a challenging task in geotechnical engineering. Typically, laboratory tests using small specimens have difficulty determining parameters due to scale dependence discontinuities and because are expensive time-consuming. Fast continuous estimation unconfined compressive σcm mass directly drilling via deep convolutional neural network (CNN) novel practical field investigation method. This paper presents CNN framework that...
Abstract The existence of joints in the surrounding rock mass has a considerable effect on tunnel rockbursts. Herein, we studied layered with different inclination angles and spacings rockburst deep tunnels investigated failure area, deformation process mass, stress change inside velocity failed rock, kinetic energy failure. type can thus be determined. results showed that intensity increases as quality designation (RQD) decreases, while rate first then decreases. exhibits turning point...
