The aim of this paper is to discuss issues based on foundation design in conjunction with partial factor format for the future development of foundation design codes. That the resistance factor approach is superior to the material factor approach in practical terms for foundation design is concluded. Then, a common procedure from geotechnical investigation/ testing to determine the design geote...

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...

Comprehensive geotechnical modelling of the behaviour of piles generally encounters setbacks: in preparing model bed simulating field conditions, of specific and uniform shear strength, and reproduction for repetitions. Due to such limitations in traditional practices, information on the complex mechanism of shaft-base resistance interaction is not adequately known. Other outcomes are: varied r...

Through coming into force of the Concrete Construction Technical Regulations [1], to the European standards were also added [2] and [3] (Attachment I.4, Standards) in civil engineering, i.e. construction and geotechnical regulations. Based on this, a need appeared for revising current technical regulations [4] and critical view of new standards. A certain number of comparable analyses on as lar...

Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...

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...

one of the main distinctions between geomaterials and other engineering materials is the spatial variation of their properties in different directions. this characteristic of geomaterials -so called heterogeneity- is studied herewith. several spatial distributions are introduced to describe probabilistic variation of geotechnical properties of soils. among all, the absolute normal distribution ...

the vital need for river management is understood and predict of bank erosion processes. almost models will not be able to evaluate bank erosion,accurately. bstem model is the most usable model in many of river engineering projects in the world. necessary data for this model are related to driving and resisting forces controlled by hydraulic and geotechnical processes. these data include geomet...
