基于单位约束组合赋权的混凝土坝性态安全评价云模型
|
摘要
针对大坝性态安全评价中梯阶逐层指标权重的不确定性、主客观组合赋权中合理配权及隶属区间模糊性等问题,提出基于单位约束组合赋权的混凝土坝性态安全评价云模型。以运行期混凝土坝为对象,在其已建性态评价体系的基础上,综合运用基于G1法和熵权法的组合赋权理论,构建了单位约束条件下性态指标组合权重寻优新方法;引入云模型概念,量化了大坝性态安全评价中评价指标的随机性与隶属区间的模糊性。将该模型应用到某实际混凝土坝工程中,其安全评价结果与其他评价模型的结果基本一致,且与大坝实际情况相符,从而验证了该模型的有效性与可行性。
A cloud model for safety evaluation of concrete dam performance based on unit constraint combinatorial weighting is proposed in this paper to tackle the uncertainties of ladder-level index weight, the reasonable weighting of subjective and objective combinatorial weights, and the fuzziness of membership interval in the evaluation. First of all, the system of evaluation indicators is built, and the weights of such indicators are given by optimum weighting under unit constraint condition combining G1 method for subjective weights and entropy method for objective weights. Furthermore, the concept of cloud model was introduced to quantify the randomness of the evaluation indicators and the fuzziness of the membership intervals. The model is applied to evaluate the safety of a practical concrete dam, and the evaluation result is consistent with the actual situation of the dam and the results evaluated by other models, which verifies the effectiveness and feasibility of the model.
