地铁隧道施工塌方风险评价的未确知均值测度模式研究

Risk assessment model of subway tunneling based on uncertained average measure theory

地铁隧道施工塌方问题一直是影响工程建设的主要问题,合理的风险评价可以较好的衡量塌方风险大小。基于未确知测度理论理论构建评价体系,并应用到地铁隧道施工塌方风险评价中。该方法考虑了塌方中的不确定因素和各指标之间的相关性,使得评价结果更为可靠,为避免或减少地铁隧道施工塌方风险的发生提供了一条有效的途径。

The tunnel collapse problem has always been the major problem of construction projects.Risk assessment is a means to measure the degree of fall risk.Present a uncertained average measure method based on the theory of uncertained measure.And the proposed method is applied to fall risk assessment,which considers uncertainties of falls and the interrelation of indicators.It provides theoretical references to prevent or reduce the fails risk of tulmeling.
