| The foundation pit engineering projects are social actives which integrate with economy, technology, management, organization. There are uncertainties in each respect of engineering projects and foundation pit engineering project need risk management. Today, risk management has become one of central issue of study in project management. Practice has proved that people should succeeded in reaching and evading the project risk, economized the cost, even increased the purpose of the profit and must implemented risk management. At first this text analyses the concept and characteristic of the project risk, and foundation pit engineering projects risks and characteristic that risk's assessing. The risk discerns the foundation that is risk management. The risk analysis and assessment are keys of risk management. The administrative decision of the risk is a core of risk management. The text tries to build the project of assessing to introduce concept, applies the entropy thought to the risk administrative system of the foundation pit engineering project, improves the efficiency of management of the risk, reduce risk degree of the administrative system.The text aims at making some discussions to the application study in the risk of the project of the foundation pit engineering with assess of entropy theory, offering the method to adopt a correct attitude towards project risk to administrative staff of the project, hoping to guide practice with it. Over static studying qualitatively in the risk is assessed on the past foundation pit engineering project, partial to subjectively in the choosing of the weight, but there are numerous random factors in reality, result and reality that were assessed to make often have disparity, for remedy in this respect assess influence of result to project risk, have introduced the concept and theory of entropy, have discussed the concrete application of entropy measurement in foundation pit engineering project, and through charge example prove superiority and wide application prospect of this method. |
