The 9th International Technical Conference on Frontiers of Hydraulic and Civil Engineering Technology (HCET24) was held from 25 to 27 September 2024 in Sanya, China. HCET2024 is organized by the China Construction Seventh Engineering Division Corp. Ltd., Henan Polytechnic University, and China, Southwest Jiaotong University, China, and is co-supported by CUG (China University of Geosciences, Wuhan); the CCCC Construction Group Co. Ltd. (Research and Development Center of Green Building Technology, CCCC), China; the China Railway Major Bridge Engineering Group Co. Ltd. (MBEC); the Institute of Rock and Soil Mechanics, Chinese Academy of Sciences; Toronto Metropolitan University, Canada; the University of Texas at Arlington, USA; Goethe University Frankfurt, Germany; and Rongzhi Science and Technology Center, China. HCET offers a global exchange platform to facilitate discussion around specific subject areas, with the goal of generating new knowledge, technology and applications in hydraulic engineering and civil engineering by forging and expanding new international communications, intercultural and interdisciplinary research networks and partnerships. The conference series continues to offer an important opportunity for modern engineering communities to share research and best practice.

This volume is a collection of the excellent contributions presented at the conference. This year, the committee received 428 submissions of international papers. All were peer-reviewed through a double-blind review process by an international panel of at least two international expert referees, and decisions were based on the research quality of the papers. A total of 199 papers from domestic and international scholars were accepted, which represents an acceptance rate of approximately 46%.

This book is organized in 8 sections according to theme: civil engineering and technology; materials for construction and civil engineering; water conservancy and hydropower engineering; geotechnical, geological and underground engineering; road and bridge engineering; transportation engineering; coal science and technology, energy and environmental engineering; and optimization, simulation technology and interdisciplinary applications. The accepted papers cover a wide range of topics, including soil-structure interaction, tall buildings, building facade systems, BIM technology, construction technology, ultra-high-toughness cement-based composites, mechanical properties of civil engineering materials, asphalt/concrete mixtures, material testing technology, physico-chemical properties of soils, flow characteristics, geographical information systems (GIS), tunnel engineering, seismic resistance, hydro power stations, coal-mine safety and management, waste to energy, double carbon, remote detection technology, and optimization design methods. The HCET2024 conference was attended by about 200 participants and consisted of a hosted opening ceremony, keynote speeches, oral sessions and poster presentations, a Q&A session, and a closing ceremony. Six invited professors shared their latest research findings, key challenges, and development trends in the keynote speeches. They are: Professor Bruno Brunone, from the University of Perugia, Italy; Professor Lei Yan, from the Earth & Space Science School (RS&GIS Institute), Peking University, China; Professor Bang-Fuh Chen, from the National Taiwan Ocean University, Taiwan, China; Professor Shuren Wang, School of Civil Engineering of Henan Polytechnic University, China; Professor Mohamed Abdelkader Ismail, from Brunel London School, North China University of Technology, China; and Professor Haijun Wang, from the Nanjing Hydraulic Research Institute, China.

Finally, we would like to thank all the experts, sponsors, and conference staff for their contributions and hard work, and for making the conference successful. We also owe our thanks to all the HCET committee members for their careful comments and advice throughout this conference, and the HCET reviewers for their valuable experience and comments. Finally, we would like to thank IOS Press for their support in producing this volume.

We look forward to seeing you at HCET2025 in Xinjiang, China.
