At 8:30 am on November 5, 2020, Professor Zhou Yanguo, a doctoral supervisor in the School of Civil Engineering and Architecture, Zhejiang University, a young top talent of the National "Ten Thousand Talents Program", and a national outstanding doctoral dissertation winner, gave an academic report on the 16D second floor of the School of Civil Engineering The department gave an academic report entitled "Discussion on seismic resilience of geotechnical engineering: from seismic damage investigation to supergravity test".

The report was presided over by Professor Yue Jianwei, Dean of the School of Civil Engineering, and some civil engineering teachers and students attended the report. The report was launched from four aspects: "Seismic toughness of geotechnical engineering", "Seismic toughness of site", "Resilience of site restoration and transmission of ground motions" and "Toughness control of sites prone to liquefaction". Professor Zhou first introduced the concept of seismic toughness, and compared the seismic toughness of different levels of materials, components, monomers, communities, cities, etc., to elicit the problems and challenges of seismic toughness of rock and soil. Then list a series of seismic damage phenomena and conduct a series of studies in conjunction with the "Supergravity Seismic Station" of Zhejiang University; through the 2008 Wenchuan earthquake liquefaction seismic damage study, a model for the shear wave velocity characterization of sand liquefaction strength based on initial liquefaction is proposed; A study on the damage of the Christchurch earthquake in New Zealand in 2010 found that the excellent frequency of the site would gradually recover after the earthquake. Based on this, it was proposed that gravel piles control the toughness of the foundation. After that, it explained the factors that affect the site's soil liquefaction and the impact of site liquefaction on the construction of the project, and used multiple examples to verify it.
