Abstract: The engineering geological environment of Chengdao in Yellow River delta is very complicated. Along with the development of oil field exploitation, it has great significance to analyse the engineering geological environmental characteristics of Chengdao. The data of bathymetry and topography, 130 boreholes, 37 flow measuring spots and wave elements of different water depth and recurrence interval of Chengdao were collected. The engineering geological environmental zoning of Chengdao was done based on analyzing bathymetry and topography, sediment distribution, physical and mechanical properties of submarine soil and marine hydrodynamics. Moreover, liquefaction of Chengdao zoning induced by wave was calculated using linear wave theory and finite element method to solve the Biot consolidation equation. The results show that the liquefaction of each zone is different mostly because of the different soil properties. And the causes of formation of geological hazard is discussed combining with wave and tide. The systematic analysis and evaluation of the engineering geological environmental characteristics and liquefaction induced by wave is helpful for engineering geological survey and foundation design of Chengdao.
