Geotechnical Lessons Learnt--Building and Transport Infrastructure Projects: Proceedings of the 2021 Ags Sydney Annual Symposium

Prof. Hadi Khabbaz has conducted original research in ground modification, unsaturated soil mechanics, tunnelling and transport geotechnics. He has been involved in design of civil infrastructure and soil behaviour modelling research for over 20 years. His research has been focused on the theoretical and numerical analysis of problematic soils, underground spaces, granular particles and unsaturated porous media with strong applications to real life engineering problems. He has made several significant contributions in the field of unsaturated soil mechanics and ground improvement techniques with fundamental and pioneering nature. His early work on unsaturated soil mechanics has been increasingly cited in literature and considered as a significant contribution to the field. He has sound numerical, experimental and programming skills. His research output and publications on geotechnical aspects of rail track foundations overlying soft soil is also extensive. To date, 17 research students completed their theses under his supervision and he has 16 completions as a cosupervisor. At present, he is the principal supervisor of 5 research students. He is an active assessor of the ARC and the Office for Learning and Teaching (OLT) grants. He is a technical reviewer of many international journals and several research organisations.

Dr. Cholachat Rujikiatkamjorn is a Professor at the Transport Research Centre, School of Civil, and Environmental Engineering, Faculty of Engineeering and Information Sciences, University of Technology Sydney, Australia. His key areas of expertise include ground improvement for transport infrastructure and soft soil engineering. He has published over 270 articles in international journals and conferences. While maintaining a strong focus on quality teaching, to date, he has secured over $2 million in research funding, mostly from external sources. He is currently a CI of one ARC-DP project, 3 ARC-LP projects, an ITTC Rail and a CRC-Rail project. He is currently the supervisor/co-supervisor of 10 HDR students and 4 Research Associates. His research achievements over the years and involvement in Port of Brisbane reclamation were the main driving force in the introduction of new Australian Standards (AS8700) on Vertical Drains in Soft Soils.

Dr. Ali Parsa is an Associate Geotechnical Engineer with more than 18 years of experience. After 6 years of industry experience, he joined University of Technology Sydney (UTS) in 2009 & worked on an industry (i.e. Menard) sponsored project incorporated different aspects of soft soil improvement. After receiving his Ph.D. in 2014, Dr. Parsa re-joined industry and since then have worked in infrastructure and construction sectors and had involvement in delivery of more than 150 projects including major infrastructure projects. In last several years, he has collaborated with leading multidisciplinary companies, many engineers from other design disciplines, variety of clients/authorities and major joint ventures in Australia. He has also been involved with several R&D programs and development of new approaches to deliver efficient & robust designs for challenging geotechnical problems. Dr. Parsa is the elected Chair of AGS Sydney Chapter. He is coordinator of AGS Sydney Chapter annual Symposium and editor of proceedings since 2017. Ali also represents Australia in two technical committees of International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), TC103 (Numerical Methods) and TC207 (Soil-Structure Interaction).

Prof. Hadi Khabbaz教授在地基改良、非飽和土壤力學、隧道和運輸岩土工程方面進行了原創研究。他已經參與了土木基礎設施設計和土壤行為建模研究超過20年。他的研究主要集中在有問題的土壤、地下空間、顆粒狀顆粒和非飽和多孔介質的理論和數值分析上，並具有強烈的實際工程應用。他在非飽和土壤力學和地基改良技術方面做出了幾項重要貢獻，具有基礎性和開創性的性質。他早期在非飽和土壤力學方面的工作在文獻中越來越多地被引用，被認為是對該領域的重要貢獻。他具有扎實的數值、實驗和編程技能。他在鐵路軌道基礎覆蓋軟土的岩土工程方面的研究成果和出版物也非常豐富。迄今為止，有17名研究生在他的指導下完成了他們的論文，他有16個共同指導的完成。目前，他是5名研究生的主要指導教師。他是ARC和OLT資助計劃的活躍評估員。他是許多國際期刊和幾個研究機構的技術審查員。

Dr. Cholachat Rujikiatkamjorn博士是澳大利亞悉尼科技大學土木與環境工程學院交通研究中心的教授。他的專業領域包括交通基礎設施的地基改良和軟土工程。他在國際期刊和會議上發表了270多篇文章。在保持高質量教學的同時，他迄今為止獲得了超過200萬美元的研究資金，大部分來自外部來源。他目前是一個ARC-DP項目的CI，3個ARC-LP項目，一個ITTC Rail項目和一個CRC-Rail項目的主要研究員。他目前是10名HDR學生和4名研究助理的指導教師/共同指導教師。多年來，他在研究成果和布里斯班港填海工程中的參與是引入新的澳大利亞標準（AS8700）軟土中的垂直排水的主要推動力。

Dr. Ali Parsa博士是一位具有超過18年經驗的副岩土工程師。在業界工作了6年後，他於2009年加入悉尼科技大學（UTS），並參與了一個由Menard贊助的項目，該項目涵蓋了軟土改良的不同方面。在2014年獲得博士學位後，Parsa博士重新加入了業界，並在基礎設施和建設領域工作，參與了包括重大基礎設施項目在內的150多個項目的交付。在過去幾年中，他與領先的多學科公司、其他設計學科的許多工程師、各種客戶/機構和澳大利亞的主要聯合企業合作。他還參與了幾個研發項目，並開發了新的方法來提供高效且堅固的設計，以應對具有挑戰性的岩土工程問題。Parsa博士是AGS悉尼分會的當選主席。他是AGS悉尼分會年度研討會的協調人，並自2017年以來擔任編輯。Ali還代表澳大利亞參與國際土壤力學和岩土工程學會（ISSMGE）的兩個技術委員會，即TC103（數值方法）和TC207（土壤-結構相互作用）。
