The conflict events that occurred in construction engineering project(CEP) often bring about a lot of adverse affection on project implementation

and show a random character.In order to find out the representing rule of conflict events in CEP

on the basis of investigation

in this paper the representing degree of conflict events in every stage is described with a new concept

i.e.the representing intensity

by combining the quantitative analysis with the qualitative analysis.Then

according to AHP

every stage's judgment matrixes of conflict events are set up

their affection on the whole construction projects from the cumulative results of conflict events in each stage have been analyzed with Latent roots of these matrixes

and the outcome is satisfactory according to the result of consistency test.At last

the distribution of conflict events during the life cycle of CEP has also been described by statistics data of the investigation.The research has obvious theoretic and practical value for forecasting conflict events

mastering the whole project situation

avoiding and reducing conflict events

and improving project management level.
