为克服传统黏弹性阻尼器与金属阻尼器的不足，提出了新型金属-黏弹复合阻尼器（metallic-viscoelastic hybrid damper，MVHD），并对MVHD力学模型的滞回性能及应用进行研究，提出了MVHD的滞回曲线、刚度方程和数值计算方法。针对所提出的新型MVHD的构造特点，分析了耗能金属梁的长度、长高比、高厚比、加载频率和耗能占比等因素对新型MVHD性能的影响规律，为MVHD的优化设计提供依据。并通过将MVHD的理论公式计算结果与数值模拟结果进行对比，相互验证了其计算方法的准确性。采用简化的非线性力学模型，对一栋采用MVHD的5层钢筋混凝土结构的抗震性能进行了分析研究。结果表明，MVHD能有效地耗散地震能量，使框架结构的动力响应显著减小。对新型MVHD设计方法所作的系统研究可为类似工程提供参考。

In this paper, the random field-Bayesian method is used to calibrate the geotechnical parameters of the slope engineering, and the stability analysis of the unsaturated soil slope considering the seepage is carried out. Regarding key geotechnical parameters as random field variables related to spatial statistics, the prior distribution of geotechnical parameters, drilling survey data and long-term monitoring data are systematically integrated, and the posterior distribution of geotechnical parameters is calibrated. The method was applied to the stability analysis of Shiliushubao landslide in the Three Gorges Reservoir area, and the results showed that the posterior mean values ​​of the calibrated geotechnical parameters were all smaller than the statistical values ​​of the original borehole survey data. The stability of the slope under the conditions of low water level and heavy rainfall in summer meets the reliability requirements, and no additional reinforcement measures are required to prevent new geological disasters. However, it is recommended that the monitoring system should be kept in working condition for a long time. [ABSTRACT FROM AUTHOR]
