<p>With the urban population increasing, conurbation is getting more and more crowed, traffic jam happens everywhere. In this case, utilization of the underground space has become an effective way to undertake this set of problems. Tunnel construction is one ...

In this study, a BIM model of shield tunnel was established to demonstrate the integration of 3D CAD with inspection records. A MRT structural maintenance database, which includes structural deterioration types, inspection records, and repair methods, was ...

<p>Shotcrete is a process where concrete is projected or &ldquo;shot&rdquo; under pressure, using a feeder or a &ldquo;gun&rdquo; onto a surface to form structural shapes including walls, floors, and roofs. The surface can be wood, steel, polystyrene, or any ...

<p>This paper reports recent advances of engineering survey operations, that is, operations of geodetic control and deformation monitoring surveys, detail mapping and geometric modelling, and setting-out and as-built surveys, for the design and construction ...

The Srisailam Water Tunnel-1 is 43.5km long as it crosses the Amrabad plateau which contains a wildlife sanctuary and the Rajiv Gandhi Tiger Reserve. This scheme has been planned since 1983 to provide irrigation facilities to the drought ridden areas of Nalgonda ...

<p>This paper describes how the concrete structure was designed and specified (concrete weight and tolerances) with allowances for the specific geotechnical and hydraulic conditions (water depth, concrete weight and freeboard, water level management in the ...

<p>In this article the author explored and evaluated the Engineering Survey System adopted for the 3.2Km TBM Tunnel of Lok Ma Chau Spur Line, a 7.5Km railway project constructed for Kowloon Canton Railway Corporation in Hong Kong, SAR from 2002 to 2006.</p ...

<p>While significant improvements have been made over the years in terms of tunnel construction in the USA, the substantial growth in passenger traffic, and the need for more efficient rapid transit systems in urban areas will involve a steady progress in ...

<p>The following article discusses the relevant material characteristics of GFRP and their influences on the design and construction of alternative TBM breakthroughs and shows possible solutions for the mentioned situation.</p>

This paper addresses application of microseismic event monitoring system in excavation of highly stressed rock mass in underground oil storage caverns. The locations and magnitudes of microseismic events were determined using a network of 12 uniaxial sensors. ...
