<p>Recent additions to the Brantford General Hospital expansion included construction of a new hospital wing, involving excavations of up to 11 metres (36 feet) depth, in loose to compact sand adjacent to an existing eight-storey hospital structure. The tendered ...

<p>We present two examples of ground deformation characterization in the metropolitan area of Vancouver using advanced InSAR. The first regards the construction of the Canada Line, an LRT system connecting Vancouver&rsquo;s International Airport to the downtown ...

The paper demonstrates the application of a hypoplastic model in class A predictions of a NATM tunnel in an urban environment. The tunnel, excavated in a stiff clay, is 14 m wide with 6 m to 21 m of overburden thickness. The constitutive model was calibrated ...

<p>Deep excavations frequently cause problems, and sometimes trigger catastrophic collapses, especially in soft clay. In principle, these problems are well understood, but designers may fall between the two stools of naive empiricism and overelaborate finite ...

Radar interferometry from the ALOS satellite captured the coseismic ground deformation associated with the 2010 Mw 8.8 Maule, Chile earthquake. The ALOS interferograms reveal a sharp transition in fringe pattern at ∼150 km from the trench axis that is diagnostic ...

<p>The deformation behavior of earth retaining wall and backside ground due to braced excavation were measured at the construction sites of Osaka Subway Line No. 8. It was observed that backside ground moved to excavation &amp; down side along a circular slip ...

Time Domain Reflectometry (TDR) is a remote sensing electrical measurement technique that has been used for many years to determine the spatial location and nature of various cable faults. In the 1950s TDR technology was adapted to locate and identify faults ...

Time Domain Reflectometry (TDR) is a versatile technology amenable to a variety of measurements and nondestructive monitoring of infrastructure conditions. It can be utilized to monitor deformation of soil/rock and structures, monitor changes in fluid levels, ...

<p>This report summarizes the findings of the first phase of a long-term research program. It provides some preliminary results and recommendations for estimating (1) the amplitude of liquefaction-induced ground displacement<br />and (2) the probability for ...
