This Keynote Paper is concerned with the fundamental mechanics of granular materials with a particular reference to non-coaxial behaviour. The non-coaxial behaviour refers to the non-coincidence of principal stress directions and corresponding principal plastic strain rate directions during plastic deformation. At present, the majority of soil models used in geotechnical practice are those of a...

Abstract. Numerous huge landslides and a lot of springs are located in Ecemiş Fault Zone between Adana and Niğde, in the south of Turkey. The waterdiscontinuity-clay trinity plays a significant role in the formation of these landslides and morphology of the area. A large-scale dam and a highway were planned in this valley where is highly rich in terms of flora and fauna and composed by huge slo...

This research work presents a case study of rock mass characterization on diversion tunnels at Diamer Basha Dam, Pakistan. Geological and geotechnical studies were performed to characterize the rock mass along the axis of diversion tunnel. The core specimens retrieved were tested in laboratory and physical and mechanical properties of the rock mass were determined. Detailed discontinuity survey...

ABSTRACT – Singapore is a city state island located off the southern tip of Malaysia Peninsula. Although Singapore is located in a low seismicity area with mild winds, it is a classic example of low seismic hazard and high exposure scenario. It is about 400 km away from a highly active earthquake belt comprising the Sumatra fault and the subduction zone. The response of a building to long-dista...

Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwate...

The seismic refraction technique provides a simplified characterization of relatively large volumes of the subsurface in 2-dimensional (distance and depth) profiles. Compression wave (p-wave) velocities, the typical measured geologic material parameter, are a function of the moduli of the various unsaturated material masses in the subsurface profile. In saturated media, p-wave velocities are in...

Seismic investigation in marine gas-bearing sediments often fails to get information below the acoustic mask created by free gas. To circumvent this problem, we combined collocated multichannel ultra-high resolution seismic imaging, electrical resistivity tomography and core sampling study physical properties of Bay Concarneau (France). We obtained sections compression (P-) wave velocity ( V P ...

This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...
