摘　　要：区间不确定性因素可能对监控模型和监控指标产生一定的影响。本文将传统的大坝安全监控模型与区间分析方法相结合,建立了可适用于区间分析的大坝监控模型,运用该模型计算了大坝区间变形监控指标,并讨论了考虑区间因素条件下大坝变形监控指标的最终确定方法。实例分析表明,该监控模型客观上更能反映大坝的实际运行性态,计算得到的监控指标更符合实际情况。The interval uncertain factors would have some influences on dam monitoring model and monitoring indexes. A new deformation monitoring model suitable for the interval analysis is built herein by combining the conventional monitoring model with and the interval analysis method, and then the model is applied to the calculation made on the monitoring indexes of the interval deformation of dam. Furthermore, the method of the final determination of the dam deformation monitoring indexes is discussed as well with the consideration of the interval factors concerned. The analysis on the actual case shows that the model can objectively reflect the actual operation behaviour of the dam; from which the monitoring indexes obtained from the calculation concerned would conform to the actual situation more reasonably.
