<p>Observations of the performance of basement walls and retaining structures in recent earthquakes show that failures of basement or deep excavation walls in earthquakes are rare even if the structures were not designed for the actual intensity of the earthquake ...

<p>Observations of the performance of many different types of retaining structures in recent earthquakes show that failures of retaining structures, including braced excavation supports and basement walls, are rare even if the structures were not designed ...

<p>Scour of rock is a complex process and can be very problematic for dams when excessive scour threatens dam stability. Removal of individual rock blocks is one of the principal mechanisms by which scour can occur, particularly in unlined spillways and on ...

The purpose of this project was to demonstrate the capabilities of mobile devices for advanced computation and analysis. bSLOPE, is a slope stability code adapted for iOS and for iPad using a new computational engine based on the work of Tabarroki (Tabarroki ...

Tectonic deformation from the 2010 Maule (Chile) Mw 8.8 earthquakeincluded both uplift and subsidence along about 470 km of the central Chilean coast. In the south, deformation included as much as 3 m of uplift of the Arauco Peninsula, which produced emergent ...

<p>At least 135 rock falls have occurred from Glacier Point in Yosemite Valley since 1870. Rock falls in 1996 and 1998&ndash;1999 led to hypotheses that these events were triggered by water system discharges from visitor facilities (leachfield and storage ...

We analyzed a combination of airborne and terrestrial LiDAR, high-resolution photography, seismic, and acoustic data in order to gain insights into the initiation, dynamics, and talus deposition of a complex rock fall. A large (46 700 m³) rock fall ...

The 2002 M7.9 Denali fault earthquake resulted in 340 km of ruptures along three separate faults, causing widespread liquefaction in the fluvial deposits of the alpine valleys of the Alaska Range and eastern lowlands of the Tanana River. Areas affected by liquefaction ...

<p>In this paper, we present a broad overview of the field case histories available for improved sites that have been subjected to strong ground shaking. This work is part of a larger research project intended to establish relationships between remediation ...

Limit equilibrium methods are evaluated with respect to their ability to predict failure of geosynthetic reinforced slope models tested in a geotechnical centrifuge. The variables considered in the centrifuge program were the reinforcement spacing, reinforcement ...
