New focus on tar sands
By many analyses, we shall soon be approaching 'peak oil' production — the time when annual output begins to stall in the face of ever-increasing demand. Oil companies are therefore increasing efforts to locate new sources and, in the face of the large-scale environmental problems caused by the failure of a deep-drilling operation in the Gulf of Mexico, the successful development of Canada's ta...
متن کاملRAM analysis of earth pressure balance tunnel boring machines: A case study
Earth pressure balance tunnel boring machines (EPB-TBMs) are favorably applied in urban tunneling projects. Despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. Reliability, availability, and maintainability (RAM) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...
متن کاملPrediction of maximum surface settlement caused by earth pressure balance shield tunneling using random forest
Due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. Estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. Many models have been established for this purpose by extracting the relationship between the settlement a...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
