博弈论在隧道及地下工程风险应对中的应用

Application of Game Theory to Risk Response Strategies in Tunnel and Underground Engineering

隧道及地下工程由于所处环境的不确定性存在着巨大的风险,如何减小不确定性,降低工程风险已成为迫切解决的问题。本文把博弈论引入隧道及地下工程,认为工程的设计和施工可看成是建设者和大自然之间的博弈行为。通过分析,可以认为上述博弈属于两人零和博弈。根据博弈论的方法,可以同时考虑工程的安全性和经济性,找到建设方在工程建设中的最优控制措施,从而达到减小不确定性,降低工程风险的目的。为了更好的理解此方法,本文给出了一个实际工程应用案例。

Due to uncertainties of the surrounding environments,there are enormous risks in tunnel and underground engineering.It is imperative to cut down uncertainties and reduce risks.To solve this problem,this paper introduces game theory into tunnel and underground engineering,which considers the design and construction as the game between constructor and nature.After analysis,the above-mentioned game can be identified as zero-sum game of two players.Based on game theory,both of safety and economy can be thought.Furthermore,optimal control measures can be found to cut down uncertainties and reduce risks.To have a better comprehensive understanding of this method,an application of the actual engineering project is given.
