...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...

... ABSTRACT: The paper refers to a field study performed to investigate the effectiveness of static preloading in improving soil conditions against excessive settlement and liquefaction. Resulted settlements were recorded and analysed. Soil conditions before and after preloading were compared...

...INVESTIGATIONS INTO THE STABILISATION OF ASH USING THE CALCITE IN SITU PRECIPITATION SYSTEM Edward S. Kucharski1, Fiona C. Chow2, Graham P. Price3, Peter R. Vaughan4 and Brian T. McGinnity5 ABSTRACT A new method of in situ ground improvement has been developed involving the precipitation of calcite...

..., erosion and other current geodynamical processes in the area, a multidisciplinary approach to investigations is required and particularly needed for any local remedial or protection measures. Our numerous papers on engineering geological investigations on unstable slopes clearly show that we have...

...EXPERIMENTAL AND NUMERICAL INVESTIGATION OF COMPENSATION GROUTING IN CLAY Jafari M. R.1, Au S. K.1, Soga K.1, Bolton M.D.1, Karim U. F. A.2, Komiya, K.3 ABSTRACT Compensation grouting is an effective way to reduce surface settlement induced by construction activities in urban areas. However...

... formations, mainly sandstones and marls, laying on highly fissured clay shales, dislocated and disarranged by an intense tectonic activity. Monitoring reveals that slow movements are developing along different shear surfaces at different depths. Site investigations and air photograph interpretation...

Allan3 ABSTRACT This paper discusses experiences in geotechnical investigation and design of several large container terminal facilities located throughout western Asia (including Sri Lanka...

...STABILITY ANALYSIS AND DEFORMATION BEHAVIOR OF LARGE EXCAVATED ROCK SLOPES Kentaro Kido1, Ryunoshin Yoshinaka2, Katsuo Hagiwara3 and Katsuji Sasaki4 ABSTRACT This paper investigates the mechanism of slope displacement using the results of long-term monitoring of the unstable behavior and failure...

... water in displaced masses by measuring one-meter depth temperature (Takeuchi, 1980). In this method of investigation, the temperature of one-meter depth on a net work of landslide area is measured; then, the map of isothermal contour lines of one-meter depth temperature will be prepared. This map can...

...GEOLOGICAL AND GEOTECHNICAL INVESTIGATION OF LAND MOVEMENT AT CITATAH AREA, WEST JAVA PROVINCE, INDONESIA Djakamihardja Achmad.S.1, Edi Prasetyo Utomo2, Subowo E. 3 ABSTRACT Citatah landslide was indicated at the section of Km 23, from Bandung Jakarta main road, West Java, Indonesia. Its...

... for safe urban development within the commu- nity boundaries can be achieved through analysis of the parameters that affect the manifestation and evolu- tion of such phenomena. The outcome of such an investigation is the compilation of detailed maps that de- fine the microzones of different landslide...

... ABSTRACT: After heavy rainfall at Kangchon-Ri in Korea on 27 July in 1996, an excavated and reinforced slope for condominium construction site was failed. To figure out the cause of the slope failure and to plan remedial works, investigation of rainfall, surface and subsurface geological...

... ABSTRACT: The construction of a bridge crossing over the Mekong River within the delta region has presented a major challenge to designers and contractors. This paper deals with the embankment design works undertaken which were based on best available investigation technology, incorporated...

This work suggested that the soil slope may have failed through an increase in porewater pressure most probably from an ingress...

... endangered human life, a state road and a brewery below it. Several methods used for the investigation and for the stability assessment of the cliff are described which had to take into account the complex rock mass conditions. Methods of terrestrial photogrammetry have been used in the investigation...

... after investigations were estimated to be much higher than was established later when problems arose during construction works. Detailed investigations of standard in-situ and laboratory tests and sets of cylindrical triaxial tests were carried out to find out reasons for the stability problems. Drained...

...GEOTECHNICAL INPUT DURING THE PLANNING PHASE Burt G. Look1 ABSTRACT Geotechnical engineers are often consulted when the site location has been decided and a geotechnical investigation is required for design input. The site investigation and assessment of the ground parameters represents the key...

... to be improved. An investigation has been performed to develop a new inclinometer device using fibre optic approach. A fibre optic cable was attached to the outer surface of a plastic pipe in two loops. Each half of the loop made up one quadrant of the circular section of the plastic pipe. As the fibre cable...

... STABILITY OF TALUS SLOPE AT LEWISTOWN NARROWS Daniel S. Ramer1, Thomas J. Imholte1, and Mian C.
