Estimation of the possible instability that may be encountered in the excavation slope(s) during the planning and application steps of the rock excavation processes is an important issue in geoengineering. In this paper, a modelling method is presented for assessing the probability of wedge failure involving new permanent or temporary slope(s) along the planned excavation dir...

The Great Baths were a large and sumptuous public building of late Roman Aquileia, with refined mosaics and inlay-work floors. Today they are completely concealed below cultivated fields, because vaults, walls and their architectural decorations were despoiled already in the Middle Age. Therefore, the university of Udine Archaeological Mission needs to employ both traditional and new technologi...

Archaeological excavation documentation poses several challenges to spatial data management. This work gives a data model, respective query functionality and the description of the resulting prototype system for recording and analyzing the data produced during the course of an excavation. Based on a requirements analysis, we develop a data model that not only captures georeferenced finds (potte...

This paper discusses the development of excavation techniques in England and their application to historical archaeology in Australia. Edward Higginbotham, a consultant archaeologist in Sydney, applies his experience of excavations in both countries to a critical analysis of various excavation methods, including test-pits, trial-trenches, the grid method, and area excavation. The advantages, ef...

During earthquake buildings which are closely spaced vibrate out of phase if there is insufficient distance between two adjacent building to accommodate maximum lateral displacement, they collide with each other this phenomenon is called as pounding. Pounding leads to verse damages to structure as the responses are drastically increased in terms of base shear, absolute acceleration, impact forc...

Barite is an important additive material to increase the weight of excavation mud. It has been used extensively in the excavation mud industry. The barite particle sizes used in excavation mud is very important. There is a direct relationship between the amount on the sift of 200 and 325 mesh. By reducing particle sizes of the 200 and 325 mesh, the specific gravity of the barite power increased...

The construction of undercrossing roads often has an adverse effect on the upper existing railway line, and can cause uneven subsidence crossed section. In response to influence new road high-speed bridge, a highway passing under bridge was taken as research object. Based FLAC3D finite difference software, computational model established analyze structural deformation bridge. results show that ...
