Text from TRB: TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 187: Seismic Design of Geosynthetic-Reinforced Soil Bridge Abutments with Modular Block Facing explores design methods and construction guidelines for using geosynthetic-reinforced soil (GRS) […]
A new synthesis report by the NCHRP aims to identify the current state of the practice in site-specific earthquake design. TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 428: Practices and Procedures for Site-Specific Evaluations […]
The Martis Creek Dam is just outside of the town of Truckee California with a population of 16,000 people, but it is also upstream about 35 miles from Reno, Nevada the gambling town with a […]
TRB’s National Cooperative Highway Research Program (NCHRP) Report 611: Seismic Analysis and Design of Retaining Walls, Buried Structures, Slopes, and Embankments explores analytical and design methods for the seismic design of retaining walls, buried structures, […]
With the events in Japan on everyone’s mind, it’s of course to be expected that seismic safety at nuclear power plants in the U.S. becomes a hot topic. This article discusses how the Nuclear Regulatory […]
The timber piles of the existing I-5 bridge over the Columbia River is vulnerable to liquefaction in the event of a major earthquake. And there is no shortage of potential sources for the shaking in […]
5 of Santa Clara’s 10 reservoirs need seismic repairs and the anticipated cost is around $150M. These dams are kept at less than capacity, and the total maximim water supply for all 10 reservoirs is […]
Any geological engineer or engineering geologist worth their salt knows that the Hayward Fault goes right through Cal’s Memorial Stadium. The stadium will be undergoing some $321 in repairs and seismic upgrades before it reopens […]
‘The Santa Clara Valley Water District has received preliminary findings from an ongoing seismic stability evaluation for Anderson Dam that detail part of the dam could experience “significant slumping” if a 7.25 magnitude earthquake were […]
A Japanese company, OYO Corporation, created the PS-suspension probe for recording P-Wave and S-Wave velocity data in geomaterials using one borehole back in the 1980’s. A recent update to the probe has made it digital. […]
