Abstract: Prof.HUANG Wen-xi gained excellent research achievements with creativity in both structural engineering and geotechnical engineering.He,pioneer of FEM,developed the method of fictitious grillage in the analysis of arch dams.He was the first to put forward a 3-D settlement analysis method of soil foundation in which the influence of the stress path was included.He was also the founder of the dynamic triaxial test,which has been well accepted by the geotechnical engineers all over the world.The Tsinghua elastoplastic model of soil founded by him is an original model of soil and has pushed forward the research of constitutive relationship of soil in China.
