Artificial neural networks analysis of Sao Paulo subway tunnel settlement data
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Artificial neural networks have been used to analyze a number of engineering problems, including settlement caused by different tunneling methods in various types of ground mass. This paper focuses on settlement over ...
Incorporating scale effect into a failure criterion for predicting stress-induced overbreak around excavations
(Elsevier, 2020)
The evaluation of the depth of brittle failure around excavations is of major importance in order to optimize the design of underground excavations and ensure the safety of workers and equipment. The current proposed ...
Proposal of Flowable Fill Designs for improvement of excavation and filling works of trenches in sanitation systems
(Institute of Physics Publishing, 2020-02-28)
Population grow in recent years requires an extension of the current pipeline sanitary system. For this purpose, granular excavation and landfill works are associated with pedestrian traffic congestion. Therefore, it is ...
A criterion for the extent of damage around excavated brittle hard rock masses in terms of its convergence over time
(CRC Press/Balkema, 2020)
When stress redistribution around deep excavations surpasses rock mass strength, several mechanical instabilities may appear, inducing damage in the surrounding rock mass, which can be observed as a convergence of the walls ...

The possible influence of astronomy on the culture of ceramic-age, pre-Columbian inhabitants of Greencastle Hill in Antigua
(Department of History, The University of the West Indies, St. Augustine Campus, 2010-04)
When Columbus arrived in the West Indies in 1492, it is reported that the Antillean Islands were inhabited by an Amerindian culture referred to as Taíno by Caribbean archaeologists. The Taíno culture was extensively ...
Analysis of the mobilization of strength parameters in brittle intact rock
(2019)
The At high-stress conditions in hard rock masses, the behavior of intact rock plays a major role in crack initiation and propagation, defining damage conditions around excavations. For modeling brittle rock behavior, the ...
