In order to analyze the viscoelastic effect of shallow-buried decomposed-rock tunnel surrounding rock deformation with time after preliminary support,the analytic solutions of equivalent elastic modulus and equivalent coefficient of confining pressure were derived adopting inverse back analysis methods firstly.

Nonlinear dynamics of artificial neural network(ANN)was used in inverse back analysis of 3-D aquifer parameters.

Aimed at knowledge of electrical equipment necessary for engineer management,this article,taking the example of AC timing windlass,introduces the relay—contact control circuit analyzing method,which is called the conversing analyzing method.

Application of the inverse analysis to the experimental study on dynamic behavior of metallic foam materials;

Application of the inverse analysis to the dynamic response test of structures subjected to intense dynamic loading;

In this paper, Based on the current SHPB, the transfer function of the system is given using the deconvolution technique in inverse analysis with computer simulation.

In this paper,through establishing model of back analysis,the modulus of deformation for foundation after dynamic consolidation can be determined by single valued back analysis method, in which the settlement modulus of deformation curve and the final drop settlement for control of soil densification are used.
