SITING STUDIES/DEVELOPMENT OF SEISMIC DESIGN CRITERIA


D’Appolonia performs siting studies for a wide range of power generation facilities and related infrastructure projects. These facilities have included large nuclear and fossil-fuel generation plants, LNG terminals and associated pipelines, gas-fired peaking electric generation stations, and hydropower and low-head hydropower developments. Typically these projects have involved comprehensive exploration of subsurface and environmental conditions based upon exploration programs that included geotechnical borings, piezometers, monitoring wells, and the application of geophysical techniques. Frequently, studies of local and regional geology, determination of design basis flood levels, environmental site assessments, and development of seismic design criteria are included in the scope of work. Based upon the results of these siting studies, the locations of whole facilities and key plant elements have been determined and design criteria for foundations and other structures have been developed. D'Appolonia has performed siting studies at plant sites in various parts of the U.S. and in countries in Europe, Asia and South America.


D'Appolonia performed siting studies for this co-generation plant.



Descriptions of D'Appolonia projects involving power plant siting and development of seismic design criteria are provided in the following:


EXAMPLE PROJECTS


Siting and Geotechnical Studies for Angra Nuclear Power Plant (PDF-624K)

D’Appolonia analyzed the stability of a failed slope adjacent to a nuclear reactor. The analysis condidered the potential seismic loading. A design was developed to stabilize the slope under seismic conditions.

Seismic Stability Analysis of Underwater Slope in Dredged Channel (PDF-503K)

D’Appolonia analyzed an underwater slope near a naval facility in Charleston, SC. Seismic loadings were developed based upon historical seismicity. The slope to be potentially susceptible to displacement as the result of an earthquake, and the predicted displacement distance was accomodated in the design.

Site Development Engineering for Power Plant Construction (PDF-1371K)

D’Appolonia performed a geotechnical site exploration program at a proposed power plant site in rural Pennsylvania. Based upon the data obtained, a site grading plan and foundation recommendations were developed.
