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...

Continuous tunneling using a tunnel-boring machine is very popular method when it comes to the construction of large tunnel projects. The use precast reinforced concrete elements, called tubbings, highly economical way secure post excavation. Unfortunately, loss load-bearing capacity has been observed in past joints between tubbings. Reasons for that are among others required reduction cross se...

For the sustainability of economic, ecological and social development, safety infrastructure, including buried pipelines, is extremely important. Undercrossing tunneling can compromise pipelines because deformations, cracks dislocations, which result in wasted resources, environmental pollution economic losses. Therefore, it important to assess pipeline response accurately during tunnel excavat...

Xiaowan Hydropower station’s dam located in south west of China is the second highest arch dam in the world (h = 292 m), its foundation is based on brittle rocks of biotite granite gneiss and amphibolites plagioclase gneiss. A largescale excavation around the foundation of the dam was conducted, near to 90 meters horizontal depth excavation and 130 meters vertical depth excavation, so the found...

Evaluation of the excavation-induced ground movements is an important design aspect of supporting system in urban areas. This evaluation process is more critical to the old buildings or sensitive structures which exist in the excavation-affected zone. Frame distortion and crack generation are predictor, of building damage resulted from excavation-induced ground movements, which pose challenges ...

Focal choroidal excavation is a choroidal pit that can be detected by optical coherence tomography. Central serous chorioretinopathy, choroidal neovascularization and polypoidal choroidal vasculopathy are pathologies associated with focal choroidal excavation. In this article, we present the follow-up and treatment outcomes of three eyes of two patients with focal choroidal excavation.

Abstract—In order to prevent encountering unpredictable factors, geotechnical engineers always conduct numerical analysis for braced excavation design. Simulation work in advance can predict the response of subsequent excavation and thus will be designed to increase the security coefficient of construction. The parameters that are considered include geological conditions, soil properties, soil ...
