In this paper, by using ODE (Ordinary Differential Equation) solver, the analysis of dynamic characteristic, seismic response and nonlinear vibration isolation for large-sized aqueduct with high pier is converted to solving ODEs\' eigenvalue problem analytically and general boundary value problem semi-analytically.

Analysis of transverse seismic responses of large scale tall pier aqueduct;

Simplifying the tall pier aqueduct as a coupled system of tall pier and rectangular tank,the transverse free vibration of the system is analyzed by using analytical methods.

The dynamic characteristic calculation of large-scale aqueducts with its fluid-solid coupling;

By compiling Matlab program,the modes and the vibration frequencies of a large-scale aqueduct are examined.

As a building of transporting water spanning rivers, large-scale aqueduct plays an important role in this water conservancy works.

Dynamic response of large aqueducts to multi-site earthquake input;

Seismic response analysis of large-scale aqueduct with double troughs;

To get the dynamic properties of the large-scale aqueduct with double troughs, brick elements with 20 nodes are used to mesh the troughs and pier for the agueduct is a complex structure and there are some influencing factors on its dynamic properties.

To the continous rigid frame bridge with high transition pier, if the side span cast-in-place section is placemented with supporter, the construction technolog.
