Port Engineering Risk Evaluation Based on Case-Based Reasoning

As China national transportation infrastructure,port engineering requires large investment,involves the expertise technology of port construction and relates to a wide range of fields,which may be quite influenced by many uncertain factors such as natural,social and environmental conditions in construction.So the investor and construction unit pay great attention to the port engineering risks.By combining with the project example,the case-based reasoning method is used to establish an evaluating index system and an evaluation model for analyzing the port engineering risk and its influencing factors.
