"Factors Effecting the Interpretation of Faulting in Cone Penetrometer Test Sounding Investigations"
Speaker: Scott Rugg, RG CEG
Cone Penetrometer Test Soundings (CPTs) are an often-used method to characterize subsurface soil behavior properties
mostly in soft material conditions. The method has many geotechnical applications, some of which include liquefaction
analysis, mapping of alluvial deposits and fill, evaluation of soil density improvement and determination of seismic
S- and P-wave velocities. When a series of CPTs is advanced, the subsurface stratigraphy can be profiled. This was
recognized early on and soon CPTs were engaged to identify stratigraphic disruptions indicative of faulting. This method
is now widely used in the coastal province of Southern California, mostly in upper Quaternary materials. Oftentimes, only
several feet or less of vertical differential across unit horizons or thickness variations in strata are used to identify
potential faulting. This means it is imperative that depth recording of CPTs are as accurate as possible. Several factors
can cause errors in depth readings, leading to erroneous interpretations of faulting. These factors will be discussed in
this presentation as well as a quality control procedure to track actual depths and thus mitigate errors. In addition,
several examples will be presented where inaccurate depth readings resulted in misinterpretation of faulting. Finally,
both the advantages and limitations of the CPT method will be discussed.
Mr. Rugg has 38 years of experience in the fields of engineering geology and geotechnical engineering, having worked on
thousands of sites throughout California and the Southwest. He has focused his vocation on fault and seismic hazard
assessment, having worked extensively on all types of projects including high-rise buildings, hospitals, water and
wastewater treatment plants, airports, dams, transportation, education facilities, and residential sites. Early in his
career he evaluated hundreds of sites damaged during the 1986 Palm Springs, 1987 Whittier Narrows, 1989 Loma Prieta,
and 1994 Northridge earthquakes. A sampling of fault hazard projects he has led are the Master-plan Investigation of
San Diego International Airport, San Diego, CA, - Mid-Coast Trolley Extension, San Diego, CA, - Airfield Expansion,
Naval Weapons Station, China Lake, CA, - Biosolids and Clarifiers Replacement, Orange County Sanitation District,
Huntington Beach, CA - Exxon Mobil Carbon Capture Facility, Baytown, Tx - Camp Blaz Satellite Facility, US Territory
Guam, and the Automated People Mover, Inglewood, CA. He has proficiency in all methods of fault investigation with
extensive experience in the use of Cone Penetrometer Test Soundings for fault hazard analysis.
