This paper studied the regional seismic tectonic characteristics, activity near-field earthquake characteristics about site of Seismic Microzonation in Shangluo City, belts and potential source zone were divided, calculating risk analysis bedrock site, surveying engineering geological conditions carrying out response zoning ground motion parameters site. The above results provide a basis for fo...

In the study we experimentally examine the influence of elastic properties and surface morphology on the inter-particle friction of natural soil grains. The experiments are conducted with a custom-built micromechanical apparatus and the database is enhanced by testing engineered-reference grains. Naturally-occurring geological materials are characterized by a wide spectrum of mechanical propert...

the uniaxial compressive strength (ucs) of intact rocks is an important geotechnical parameter required for designing geotechnical and mining engineering projects. obtaining accurate estimates of the rock mass ucs parameter throughout a 3d geological model of the deposit is vital for determining optimum rock slope stability, designing new exploratory and blast boreholes, mine planning, optimizi...

The research progresses in static and dynamics tests, constitutive models, interface elements, model tests and field tests of pile soil interface are summarized, and the problems and deficiencies in the current research are analyzed. It is pointed out that research on the dynamic characteristics of pile soil interface widely seen in practical engineering are in lack. Especially, big size experi...

Geological engineers have mostly been involved in geotechnical problems since the beginning of 19 century. Engineering geological maps and field data are needed to solve these problems. The amount of data for these maps is extremely large, so putting all the map elements on the map sheet causes difficulties while solving problems. The magic words, Geographic Information System (GIS) is a tool f...

This paper presents engineering geological investigation results in the form of rock mass characteristics for tunnel number 1 Sigli-Aceh toll road. The was carried out through mapping, core drill evaluation, and laboratory tests. In this research, rating (RMR) Geological Strength Index (GSI) were applied classifications. measurement quality is then used to determine excavation method support sy...

Based on the Markov model and the basic theory of information entropy, this paper puts forward a new method for optimizing the location of observation points in order to obtain more information from limited geological investigation. According to the existing data from observation points data, classification of tunnel geological lithology was performed, and various lithology distribution were de...

This paper presents the results of a geological engineering investigation in form rock mass characterization at Jlantah Dam Intake Tunnel. The study was carried out through technical mapping, core drill evaluation and supported by laboratory test data. determination classification research site has been using Rock Mass Rating (RMR) method, but it is necessary to use another method that more sui...

reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. in this regard, this research deals with development of a 3d geological engineering model on mashhad city soil using sequential gaussian simulation (sgs) approach. the intense variability of soil in the study area has sometimes caused serious problems in civil engi...
