At this time, there is a crisis associated with concern over the safety of tailings dams and lack of trust in their design and performance. This crisis has resulted from recent high-profile failures of dams at locations with strong technical experience, conscientious operators, and established...

Abstract. Assessment of geological hazards in urban areas must integrate geospatial and temporal data, such as complex geology, highly irregular ground surface, fluctuations in pore-water pressure, surface displacements and environmental factors. Site investigation for geological hazard studies...

Geotechnical hazards along linear transportation corridors are challenging to identify and often require constant monitoring. Inspecting corridors using traditional, manual methods requires the engineer to be unnecessarily exposed to the hazard. It also requires closure of the corridor to ensure...

The Inaugural Lumb Lecture was delivered on May 10, 2000, by Professor Norbert R. Morgenstern of the University of Alberta, Canada, at the Hong Kong Convention and Exhibition Centre. The title of the lecture was "Performance in Geotechnical Practice".

The traditionalconcepts that constitute the framework for geotechnical engineering are often insufficient on their own to provide a basis for solving geotechnical problems associated with frontier resource developments. Studies are reported on the creep of permafrost slopes, the mechanics of...

In deep underground excavations in hard rocks where stresses easily exceed the micro-crack initiation stress level inside the rock mass, proper consideration of the behaviour of rockmass during the brittle fracturing process in constitutive modelling is of paramount importance. Current empirical...

Heavy rains spread over some interval preceding large landslides in sensitive glaciomarine clay in eastern Canada are often noted as a triggering or causative factor in case studies or research reports for individual landslides, although the quantity or duration of the triggering rain event has...

The purpose of this study is to evaluate the use of motion capture instrumentation to monitor the response of a railway embankment and the underlying soft peat mire foundation soils to freight train loading. Initial data sets were obtained from the motion capture system, called the...

Abstract: When sandy soils respond in a strain-softening manner to undrained loading, an estimation of the resulting undrained shear strength (S-u) is required to determine the potential for flow liquefaction at a given site. One of the most commonly used methods for estimating the undrained...

Tests on small circular openings have been conducted to investigate the deformation processes near tunnels at large depth or in weak rock. The test equipment has been described in Part 1; typical test results documenting the behaviour of small tunnels in a jointed rock mass with time-dependent...
