The rock mass deformation modulus, Erm, is an input parameter for most numerical modeling to verify the behavior of rocks due engineering activities within/on it. Among common methodologies used estimating this parameter, empirical correlations based on classification schemes (e.g., RQD, RMR, GSI, and Q) stand out most, principally because their low cost when compared other methods. Herein, mai...

One hundred seventy geotechnical boreholes, two geo-seismic profiles of multichannel analyses surface waves (MASW), and geoelectrical cross-sections electrical resistivity tomography (ERT) were carried out in the historical Diriyah urban zone. The borehole samples analyzed for parameters standard penetration test (SPT N-value), rock quality designation (RQD), compressive strength (CS). Moreover...

Geological storage is an important concept for high-level radioactive waste (HLW) disposal, and detailed studies are required to protect the environment from contamination by radionuclides. This paper presents a series of geomechanical studies on the site selection for HLW disposal in the Alxa area of China. Surface investigation in the field and RQD analyses on the drill cores are carried out ...

Applications and services in ubiquitous computing systems often interact in a context-dependent, reactive manner. How information flows, and what services communicate when, is determined by the context of the physical space, the context of users, and the services that are available. Existing discovery systems provide basic facilities for finding services based on their static descriptions in th...

Abstract To obtain rockburst characteristics at rock engineering, the event, in situ stress characteristics, and proneness are studied a deep gold mine. The severity of increases with cover depth main locations spalling events include roof sidewall. measurement results show this area that is controlled by horizontal constructional pressure, self-weight also has an important influence. mechanism...

Flysch materials are one of the most challenging geological and often give rise to slope instability problems. Due its natural heterogeneity, geomechanical characterization flysch is somewhat difficult. The Spanish Basque Arc Alpine region a very well-known location for materials. In this paper, an area approximately 100 km2 in intensively studied their geomechanically characterized. A total 33...

In order to solve the problem that current geophysical method is difficult locate in mud of bored piles, effective exploration karst caves at bottom author puts forward application Internet Things technology and sonar construction pile foundation a high altitude environment. Combined with propagation characteristics stress waves, detection for piles proposed, detector (JL-SONAR) signal analysis...
