Caofeidian Port is the only deep-water port under construction in northern Yangtse River estuary in east China coast. Following vast industrial constructions, unexpected environmental change could possibly have a disadvantageous influence on some projects and future development. This paper, based on a comprehensive analysis on the geological environment and baleful geological processes, suggests that the economic development in Tangshan City necessitates evaluating the geological environment, bringing preventing and controlling geological disasters as a long-term task into the development and management system at Caofeidian Port.
