| 摘 要： | 混凝土坝坝体裂缝安全监测在大坝安全监控中具有十分重要的地位.传统基于原始监测数据的指标拟定方法如典型小概率法、置信区间法等具有自身的局限性,采用基于概率论与数理统计理论与模糊集合理论交叉融合基础上形成的云模型拟定大坝裂缝宽度安全监控指标,在拟定安全监控指标的同时,也计算出了其代表大坝出现险情的确定度,实现定量-定性-定量的相互转换,可更好地指导工程实践.

| Abstract: | The safety-monitoring of cracks on the concrete dam is very important in the concrete dam safety- monitoring, since the cracks are very harmful to the dam. The traditional methods based on original monitoring data such as typical small probability method and confidence interval approach, have their limitations. The article adopts the cloud model based on the combination of probability theory, mathematical statistics and fuzzy set theory into the determination of dam safety-monitoring indices. The method formulates the degree of certainty of whether the dam is in danger at the time of calculating the indices realizing the ＂Quantitative-Qualitative-Quantitative＂ transition. The cloud model can be further applied and verified in engineering practices, in the future. |
