Inversion Identification Method and Mechanical Characterization Based on Experimental Data

本文给出了两类基于实验(实测)数据的反演识别方法,简述了其在界面力学性能及工程实测数据分析中的应用。在粘接界面力学性能的反演识别实验研究中,基于不同加载速率的实验曲线,结合参数化界面力学模型,通过反演识别给出粘接界面力学性能参数,并对识别结果的适定性进行独立的实验验证;在基于工程实测数据的反演识别与力学建模方面,在分析盾构装备载荷特点的基础上,对海量的实测数据统计分类,提出了力学量纲分析的建模方法,并应用于盾构掘进载荷的反演识别研究。

Inversion identification method based on both experimental data and on-site measured data is proposed in this paper.Its application examples in interface mechanical properties and engineering on-site data analysis are also briefly demonstrated.In the experimental study of bonded interface mechanical properties by inversion identification,the mechanical property parameters of bonded interface are given,based on experimental curves obtained at different loading rates and combined with the parameterization interface mechanical model.Then the well-posedness of identification results was verification through a independent experiment.For the inversion identification based on engineering on-site measured data and mechanical modeling,statistical classification of mass on-site measured data was carried out based on the load characteristics analysis of shield tunneling machine,and a new mechanical modeling method was proposed by dimensional analysis.The method was applied to inversion identification for shield tunneling machine.
