In response to the complex risk factors and difficulties in risk identification and management in overseas port construction projects,risk identification,risk level assessment,risk trend analysis,and risk correlation research have been conducted.Engineering statistical information extraction and quantitative analysis methods are adopted to extract 24 risk events from 73 overseas port construction projects.The occurrence probability,processing cost,and project delay of each risk event are calculated to draw a development trend chart.By applying conditional probability calculation and regression analysis methods,the correlation among risk events is determined,and three risk chains are finally obtained.The research results indicate that extreme high temperatures,tidal changes,changes in property owners,import restrictions,and caisson transportation and installation are high-risk events.Since 2017,the occurrence probability of natural and social environmental risks has shown an upward trend,the cost of handling extreme heat risks has significantly increased,and the delay in construction caused by owner and social risks has significantly increased.Chinese project managers can use methods such as improving contract details,strengthening preliminary planning discussions,and cooperating with design to develop material substitution plans to control the top nodes in the risk chain and curb the spread and propagation of risks.
