Macan Doroudian, Ph.D., P.E.

Dr. Doroudian is experienced in the fields of geotechnical engineering, foundation engineering, and geotechnical earthquake engineering. He has worked on projects ranging from geotechnical and ground motion assessments for earth dams, stabilization of large landslides, moisture intrusion through slab-on-grade concrete floor, failure analysis of mechanically stabilized earth retaining walls (with soil nail anchors and geogrid reinforcement), soil erosion associated with landfill cover, and construction vibration monitoring, damage potential assessment associated with such vibrations, and pipeline failure investigations. Dr. Doroudian has also performed geotechnical engineering analysis for more than 400 telecommunication facility sites. In addition, he has extensive laboratory soil testing experience ranging from development of a special device for measuring small-strain behavior of soils (one copy is currently used at University of Rome, Italy) and development of special equipment for sample preparation from wide-diameter tubes for triaxial testing, to special techniques for centrifuge testing of soil nailed excavations models under cyclic loads. He is also experienced in Geotechnical field instrumentation of measuring equipment such as tiltmeters, inclinometers, piezometers, geophones, and seismometers. Dr. Doroudian is currently serving on the ASCE Standards Committee KSTAT (Fitting of Hydraulic Conductivity with Statistical Spatial Estimation).

Dr. Doroudian’s major areas of research include; development of a GIS-based geotechnical database for seismic microzonation for Southern California Earthquake Center (SCEC) and University of Zagreb, Croatia. He has performed joint research with an international team on evaluating the socio-economic impact of large earthquakes, using a combination of GIS-based geotechnical database and nonlinear I-D site response effective stress analysis to evaluate the effect of local geologic conditions and soil type on seismic response. Other major areas of research have been small-strain behavior of soils in NGI direct simple shear test; centrifuge testing of soil nailed excavations models under cyclic loads; and settlement of compacted fill under seismic and similar cyclic loads.
