学术报告:Rapid characterization of stress-strain behavior for unsaturated soils 打印
2016-06-14

主讲人:Professor Zhang, Xiong
主持人:陈仁朋教授
时间:2016年6月17日周五9:30~10:30
地点:风洞会议室
Dr. Xiong Zhang:Associate professor in the Department of Civil Engineering, and Architectural Engineering, and Construction Management, College of Engineering and Applied Science, University of Cincinnati.His studies focus on development of advanced laboratory techniques to rapidly characterize geomaterials, constitutive modeling coupled hydro-mechanical behavior of unsaturated soils, numerical modeling of climate-soil-structure interaction, slope stability analysis, soil stabilization and ground improvement, and frozen ground engineering. He was one of the two speakers of ASCE GeoInstitute Unsaturated Soils Committee Webinar on “Introduction to Constitutive Modeling of Unsaturated Soils.” Dr. Zhang is currently serving as anAssociate Editor for Geomechanics and Engineering, An international Journal and committee member of several nationwide technical committees such as TRB AFP60 Committee on Engineering Behavior of Unsaturated Soils, TRB AFS20 Committee on Soil and Rock Instrumentation, and ASCE Geo-Institute Pavement Committee and Shallow Foundation Committee.
Suction- controlled tiaxial (SCTX) tests are considered to allow researchers to investigate influences of individual variables on unsaturated soils under specified stress path with controls of stresses, pore water and air pressures. This presentation discusses the limitations of the SCTX tests in the characterization of unsaturated soils. A possible solution to the problem was proposed based on a newly developed modified state surface approach (MSSA). It is proposed that results from undrained (constant water content) tests be used to replace the SCTX tests for the constitutive modeling purpose. Not only can it produce theoretically correct results with much simpler testing equipment, but also significantly reduce the testing time (from 2-3 months/test to 2-3 hours/test). This can potentially leads to extensive applications of unsaturated soil mechanics in routine engineering projects.

学术报告:Performance of Multi-Axial Paving Interlayer Reinforced Asphalt Pavement 打印

地点:风洞会议室
Dr. Jenny Liu:Professor in the Department of Civil and Environmental Engineering at the University of Alaska Fairbanks. Over the last ten years she has secured over 10 million dollars of research funding to support her research in infrastructure materials and pavement engineering. She is the Director of Center for Environmentally Sustainable Transportation in Cold Climates. She is currently serving as an Associate Editor for American Society of Civil Engineers (ASCE) Journal of Materials in Civil Engineering, Chairman of ASCE Bituminous Materials Committee, Director of American Concrete Institute (ACI) Alaska Chapter, and members of Transportation Research Board (TRB) committees of AFP70, AFK30, and AFK50, and ASCE committees of Highway Pavement and Geo-Institute Pavements. She received Alaska Society of Professional Engineers’ 2016 Engineer of the Year Award.
Paving interlayers have been used in asphalt concrete (AC) overlays for a variety of benefits.In cold regions such as Alaska and other northern states, pavements are more prone to distresses due to extreme climatic conditions. A study has been conducted to explore how paving interlayers function in AC pavements in Alaska. Laboratory investigation of the performance of asphalt mixtures reinforced with three types of paving fabrics: two biaxial fabrics and one newly developed multi-axial reinforced paving composite was presented. The reinforcing effect of the multi-axial interlayer on the entire pavement was further investigated through pavement structural analysis, finite element method (FEM) analysis, and surveys from field test sections.
