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.

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.

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.

Based on the specific situation in the process of computing the superelevation transition the horizontal curve of highway, this article gives the universal calculation for the superelevation transition within the superelevation run\|off, conforming to the requirments in Specification for Design of Highway Alignment.

Presently the method of roadway superelevation transition(run-off) is not stipulated clearly in the Highway Route Design Specification in China.

With regard to the setup of road superelevation,this paper proposed that the superhigh values be rationally decided on in accordance with the requirements upon horizontal force coefficient,road longitudinal gradient and curve location,and illustrated the relationship between them and clothoid and widening transitory section by calculating the length of superhigh transition section.
