Liping Yan, Ph.D., PE, GE
Geotechnical Engineering Group
Los Angeles Department of Water and Power
Liping Yan graduated from the Southwest Jiaotong University located in
Sichuan, China, in 1983 with a B.Eng. Degree, majoring in bridge structural
engineering. He received an M.Eng. Degree in geotechnical engineering
from the same university in 1986 and came to U.S. for further study. He
earned M.S. (1990) and E.D. (1992) from the California Institute of
Technology, and Ph.D. (1998) from the University of Southern California, all
Dr. Liping Yan's research projects have related to soil constitutive relations,
numerical analysis on seismic stability of earth dams and embankments,
dynamic analysis on soil-structure interactions, and development and
implementation of improved seismic design and retrofit procedures for
bridge abutments and footings.  He has authored and co-authored over
forty scholarly publications.  

Since 1990, Dr. Yan has been consulting for both public and private clients.
 He has been involved in or has managed a variety of projects, such as
reconstruction of I-10 Freeway bridges at Fairfax and Washington
Boulevards after the Northridge earthquake in January 1994, Port of Los
Angeles 2020 Plan, California Statewide Bridge Retrofit Program, Alameda
Corridor, Metro Gold Line, and Los Angeles Reservoir Water Quality
