| 摘 要： | 以大坝安全监测资料为基础,以大坝安全状态为系统物元,利用物元理论、可拓集合理论及其关联函数,确定了大坝安全状态的经典域和节域,建立了大坝安全可拓学综合评价模型,并以综合评价体系中的"变形"为例,给出了一个可拓学综合评价算例.算例表明:采用可拓学理论来对大坝安全进行综合评价是合理、可行的,为大坝安全综合评价从定性评价到定量评价、从单指标评价向多指标评价提供了一条全新的、更为科学合理的思路和方法.

| Abstract: | According to the data of dam safety monitoring, regarding the state of dam safety as matter-element of system, based on matter-element theory, extension set and dependent function,the classical domain and joint domain of dam safety state is decided;and a comprehensive assessment model of dam safety is established by extenics theory; and a practical example of comprehensive assessment by extenics theory is given with comprehensive assessment system's deformation as an example. The example indicates that the adoption of extenics theory in comprehensive assessment of dam safety is reasonable and feasible. It provides a new and more scientific thought and method to assess the dam safety comprehensively from qualitative assessment to quantitative assessment and single index assessment to multiple-index assessment. |
