... ABSTRACT: The stability of tunnels constructed in clay with overlying layers of coarse grained soil is examined using data from centrifuge model tests. Results show that the stability of a tunnel in the lower clay layermay be influenced by the presence of an upper layer depending on the type...

... ABSTRACT: The paper presents the results of physical (geomechanical) model investigation of fractured rock behavior for validating the overall stability of openings excavated in the rock massif for a power house of a hydropower plant. Three types of tests were performed by geomechanical...

... the technology associated with the three techniques enable design engineers to address stability problems over a range of scales and in a range of geomechanical environments. The techniques have similar aims but have developed into separate disciplines with unique attributes. The procedures for designing...

...AN INVESTIGATION OF LONG-TERM STABILITY OF A SOIL NAILED EXCAVATION USING CENTRIFUGE MODELLING Alun M.C. Jones1 and Michael C.R Davies2 ABSTRACT Soil nailing is an earth retaining technique used to stabilise existing slopes and support excavations. The stability post construction can change due...

... BRIDGE APPROACH SUPPORTED ON EMBANKMENT PILES Sek-Kwan Tang and Thian-Loke Lim1 ABSTRACT Building a high embankment on soft alluvial deposits within the constraint of a short construction period has always posed challenges to geotechnical engineers. Other than stability, settlement...

T The increase in shear strength was also assessed in terms the measured settlement and applying soil mechanics theories. BACKGROUND The My Thuan Bridge site is located along the northern arm (Tien Giang...
