Anadolu topografyası geçirdiği jeolojik evrimi sebebiyle engebeli bir morfolojiye sahip olup mühendislik yapılarının çalışıldığı alanlarda şev yarmalarının oluşmasına sebebiyet vermektedir. Bu bağlamda, Batman ili sınırları içerisinde kalan Batman-Mardin Yolu üzerindeki yüksek kaya şevleri farklı analiz programlarıyla çalışılmış programlar karşılaştırılarak ortamındaki duraylılığının ortaya kon...

Three-dimensional stability of roofs in deep flat-ceiling cavities is analyzed. The number, factor safety, and required supporting stress are used as measures roof stability. Despite the simplicity flat geometry, three-dimensional analysis presents some complexities owed to shape failure surface geometry collapse mechanism. mode assumes a rock block moving downward into cavity, study aims recog...

The deep underground roadways are widely used in the mining industries at present, but relevant theoretical bases not fully understood. In this paper, numerical solutions for strain-softening surrounding rock under generalized three-dimensional (3D) Hoek-Brown (GZZ) strength criterion developed incorporating confinement-dependent characteristics of <math xmlns="http://www.w3.org/1998/Math/MathM...

Damage in a rock mass is heavily dependent on the existence and growth of joints, which are also influenced by complex stress states induced human activities (e.g., tunneling excavation). A proper representation loading path essential for understanding mechanical behaviors masses. Based discrete element method (DEM), influence cracking process specimen containing an open flaw examined. The effe...

Vipingo quarry in Kilifi county, Kenya, is one of the quarries supplying coral limestone for manufacturing coastal region. Due to its close proximity Indian ocean, semidiurnal ocean tides tend have an influence on stability slopes adjacent shoreline. Finite element numerical analysis using generalized Hoek–Brown criterion conducted assess condition followed by slope-angle optimization determine...

The effect of large deep foundation excavations on the surrounding existing tunnels is a problem that cannot be avoided in current construction background. This difficult to assess precisely, especially when geometry and pits complex. In this paper, three-dimensional (3D) finite element model has been developed based case containing four complex intersecting pit. used hardening soil with small-...

A jointed rock mass presents a more complex design problem than the other rock masses. The complexity arises from the number (greater than two) of joint sets which define the degree of discontinuity of medium.  The condition that arises in these types of rock masses is the generation of discrete rock blocks, of various geometries. They defined by the natural fracture surfaces and the excavation...

Abstract The high temperature and in-situ stress geological environment can significantly affect the mechanical properties, failure modes, deformation characteristics of deep shale reservoirs. In this study, real-time triaxial compressive tests simulating formation (temperature: 25–150 °C, confining pressure: 0–100 MPa) are carried out. GSI-strength degradation constitutive models derived based...

We took into account the adverse influence of karst water seepage effect on water-resistant rock mass tunnel face. Based upper-bound theorem limit analysis and Hoek–Brown failure criterion, we obtained calculation method critical safety thickness mass. carried out a feasibility analysis, an influencing factors comparative with previous related research achievements this method. The results show...
