sakiabad is one of the most important sites in the choqakhor pond’s basin which show remains of nomadic settlement in the chalcolithic period. salvage excavation was carried out for two months during autumn and winter of 2011. by digging of five trenches10×10 m, one of the nomadic settlements was exposed with mud and stone architecture made from the local materials in the region. exposed space ...

The site of Wonderwerk Cave, located in the Northern Cape Province between the towns of Danielskuil and Kuruman, preserves an extraordinary sequence that spans close to 2 million years of hominin activity (see Chazan and Horwitz, this volume, for an overview of the site). The earliest phases of occupation have only been recovered in Excavation 1 near the front of the cave in excavations carried...

The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...

We report on a study carried out within the 3D MURALE project, in which the complete workflow necessary for automatic recording, reconstruction and interactive visualization of artefacts on archaeological excavation sites has been tested. With state-of-the-art technologies from digital photogrammetry, computer vision and computer graphics a prototypical pipeline for recording, 3D modeling and v...

This paper describes the design, construction and early performance of a retaining structure close to a subway tunnel in Barcelona. The excavation, about 16 m deep, was carried out in 2001 during the construction of a new hospital, and involved a rectangular area with the longer side (170 m) almost parallel to the tunnel. The design had to fulfil two requirements: first, the influence of the ex...
