In order to open out the distribution rule of morbidity phenomena in engineering project, 571 project managers in 33 construction companies have been investigated and visited for obtaining a large amount of information of morbidity phenomena. According to the information, all kinds of morbidity phenomena and their frequencies are summed up, their primary and secondary relationships and distribution rules in every stage are described by means of statistics; and then, their characteristics together with investigation results are explained. Third, morbidity phenomena´s total distribution in engineering project and its mathematic characteristic are analyzed according to sub-sample capacitances of all morbidity phenomena in four stages. It can be known that the research result would be a confirmatory evidence for project managers to forecast project morbidity, making project plan and optimizing project resources, as well as controlling whole project in macro-angle.
