The main research works are as follows:1) It is difficult to evaluate the vibration response of the "train-bridge-structure" integrated complex system.

The method of mode superposition is applied to the analysis of dynamic response of vehicle structures in this paper.

This thesis analyzes the vehicle structure in the road transportation, researches the replaceable relations among various passenger vehicles and expoundes the vehicle structure forecast model of based on replaceable relationship, the model is effect by forecast the vehicle structure of Changchun and Siping in the furture.

Mode parameters identification of bridge structure under different quaking methods;

Environmental encouraging method of bridge structure mode parameters identification;

On earthquake damage and aseismic design method of bridge structure;

Identification on physical parameters of bridge structures based on extended Kalman filter;

General situation survey of development of optimal design of bridge structures;

State of arts on state parameter monitoring of bridge structures;

Identification of operational bridge structure responses using statistical learn theory

Displacement back analysis of tunneling construction control is applied to the parameter calculation of construction alignment control in longspan PC cantilever bridge.

This paper summarizes the theoretical research and developmental actuality about librating control system for bridges .

Due to the advantageous properties of FRP materials, FRPs have found increased applications in bridge construction in recent years,and have obtained plenty study result.
