主讲人简介：

徐世烺，结构工程专家，浙江大学教授，生于陕西省柞水县。1977年毕业于西北农林科技大学水利工程专业。1982、1988年先后获得大连理工大学海洋工程硕士、结构工程博士学位，获国家教委和国务院学位委员会联合授予“中国有突出贡献的博士学位获得者”荣誉称号。2021年当选为中国科学院院士。

主要从事高性能混凝土结构和材料研究工作。创立了具有重要国际影响力的混凝土双K断裂理论，提出了混凝土结构完整性安全评价准则，建立了系统的混凝土裂缝安全分析理论和测试技术体系，领导制定了《用楔形劈裂试验和三点弯曲梁试验确定混凝土裂缝扩展双K准则的试验方法》国际标准。双K断裂理论成功应用于乌江东风混凝土高拱坝、乌江索风营重力坝、长江三峡大坝二期工程和三期工程、南水北调中线水源工程丹江口大坝加高工程裂缝完整性评定和裂缝控制，为重大水利水电工程安全运营提供了重要技术支撑。研发了高韧性混凝土及复合控裂结构，为基础设施安全服役提供了技术保障，实现混凝土抗裂性能和耐久性能大幅提升。发明的高韧性混凝土成功应用到上海吴淞军港、浙江新岭隧道、舟山鱼山跨海大桥、杭州秋石高架桥等15项重大工程。获得国家自然科学奖二等奖、国家技术发明奖二等奖、国家科技进步奖三等奖各1项及省部级自然奖和发明奖一等奖4项。

Brief Introduction of Professor Shilang Xu

Shilang Xu is an expert in Structural Engineering and a professor of Zhejiang University. He was born in Zhashui County, Shaanxi Province.

Professor Xu graduated from Northwest A&F University with a major in Water Conservancy Engineering in 1977. In 1982 and 1988, he successively obtained the master's degree of Marine Engineering and the doctor's degree of Structural Engineering from Dalian University of Technology.

Professor Xu was jointly awarded the honorary title of "China's Outstanding Doctoral Degree Recipient" by the State Education Commission and the Academic Degrees Committee of the State Council. In 2021, Professor Xu was successfully elected as an academician of the CAS Member.

Professor Xu mainly engages in research on structures and materials of high-performance concrete. He founded the Double-K Fracture Theory of concrete with significant international influence, proposed safety evalsuation criteria for structural integrity of concrete, established a systematic theory and testing technology system for concrete crack safety analysis, and led the development of the international standard "Test Method for Determining Double-K Criteria for Concrete Crack Expansion Using Wedge Splitting Test and Three Point Bending Beam Test".

The Double-K Fracture Theory has been successfully applied to the Wujiang Dongfeng Concrete High Arch Dam, Wujiang Suofengying Gravity Dam, the second and third phases of the Yangtze Three Gorges Dam, and the Danjiangkou Dam Heightening Project of the Middle Route of the South to North Water Transfer, providing important technical support for the safe operation of major water conservancy and hydropower projects.

Professor Xu has developed high toughness concrete and composite crack control structures, providing technical support for the safe service of infrastructure, and achieving significant improvement in concrete crack resistance and durability. The invented high toughness concrete has been successfully applied to 15 major projects, including Shanghai Wusong Military Port, Zhejiang Xinling Tunnel, Zhoushan Yushan Cross Sea Bridge, and Hangzhou Qiushi Viaduct and so on.

Professor Xu won the second prize of the the State Natural Science Award, the second prize of the the State Technological Innovation Award, the third prize of the National Science and Technology Progress Award, and four provincial and ministerial natural awards and the first prize of the invention award.
