limitations in the design method used for the support systems of urban buildings make them vulnerable to damage by adjacent excavations. this paper examines a traditional system used to support excavation sites and adjacent buildings in which inclined struts are connected to the wall or foundation of the adjacent building. this method can be considered to be a type of shoring or underpinning. t...

The mechanical evolution of coal is evident when the pore pressure and surrounding stress alone influence it. However, response saturated under coupling effect confining needs further investigation. This study identifies behaviors burst tendency dry condition where simultaneously increase but keep constant difference by conducting a series triaxial compressions on high samples. results show tha...

This paper presents a three-dimensional slope stability limit equilibrium solution for translational planar failure modes. The proposed uses Bishop’s average skeleton stress combined with the Mohr–Coulomb criterion to describe soil strength evolution under unsaturated conditions while its formulation ensures natural and smooth transition from saturated regime vice versa. analytical is evaluated...

This paper presents the results of a numerical analysis impact rock mass geomechanical parameters on stability preparatory headings located within Legnica-Glogow Copper District. The shows calculations prepared for driven in two types with different strength and deformation parameters, which allow illustrating their influence safety mining performed underground copper ore mines. Numerical model...

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

Mudstone is a widely occurring type of rock in deep mining, and it crucial to understand its failure mechanisms strength characteristics under the interaction water high stress ensure stability deeply buried engineered mudstone. In this study, composition structure mudstone were obtained, triaxial tests conducted on five different contents four confining pressures using servo press. The variati...

This work presents a new damage criterion suitable for elastic, elastic-plastic/viscous or elastic-viscous-plastic materials involving rupture effects. Its derivation, made here within thermodynamic framework, follows previous scalar-valued mechanics approaches. Such approaches are appropriate to many geophysical problems quasi-brittle which there is no clear physical justification the level of...

One of the main challenges fusion reactors based on magnetic mirrors is axial particle loss through cones. In multi-mirror (MM) systems, addressed by adding mirror cells each end central cell. Coulomb collisions in MM sections serve as retrapping mechanism for escaping particles. Unfortunately, confinement time this system only scales linearly with number and requires an unreasonably large to s...
