2016软土工程前沿论坛在我校成功召开
2016-09-21
为了给从事软土工程理论研究和实践的学者提供一个深入交流、学习的机会,展示我国软土工程和相关交通基础设施最新的基础理论及相关技术,推动软土力学基本理论研究和应用,中国土木工程学会土力学及岩土工程分会软土工程专业委员会于8月26~28日在湖南长沙湘府路西雅国际大酒店召开了“软土工程前沿论坛”。本次论坛由湖南大学和浙江大学承办,长沙理工大学、湖南科技大学、湖南工业大学、国防科技大学、中南林业科技大学、中南大学、湖南省交通规划勘察设计院及湖南省交通科学研究院等单位协办。共有140余位注册代表出席论坛。

湖南大学曹一家副校长,中国土木工程学会土力学及岩土工程分会副理事长、重庆大学刘汉龙副校长,专委会黄茂松主任在开幕式分别致辞。论坛邀请了华东建筑设计研究院王卫东院长、天津大学建筑工程学院郑刚院长、东南大学刘松玉教授、广东水利水电科学研究院名誉院长杨光华教高、广西大学长江学者梅国雄教授等软土工程领域7位专家学者做了内容丰富的特邀报告,内容涉及软土原位测试、软土深基坑及盾构隧道开挖、超高层建筑沉降、软土预应力管桩抗震等方面最新理论和技术。与此同时,20余位来自全国各地及湖南省高校的专家学者作了专题报告。

在两天的会议中,参会代表对软土工程的前沿问题进行了热烈充分的讨论。论坛加深了代表对软土工程的认识,加强了湖南省岩土界以及与全国领域前沿专家的交流,取得了圆满成功。
学术报告:Rapid characterization of stress-strain behavior for unsaturated soils
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
2016-06-14

主讲人:Professor Jenny Liu
主持人:黄立葵教授
时间:2016年6月17日周五10:45~11:45
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.
