Finite element analysis of reinforcement scheme of Changsha dam and its safety evaluation;

Study on the reinforcement scheme of the slant-legged rigid frame arch bridge;

The cause of the diseases has been found out through the present situation diagnosis,as well as with the theoretical analysis of the original design and the examination result,and the thinking of reinforcement design and the control factors,the four reinforcement plans have been studied,and the plan of a 7 cm integrat.

Through the utilization fuzzyoptimal theory, the fuzzy optimal models of bridge reinforcement plan with multi-layer and multi-objective are established, thus the relative optimal membership degrees of plans are got.

The characteristic of pit,enclosing structure scheme and supporting system,and reinforcing scheme are introduced one by one in the paper.

According to the present conditions of the Xigang Bridge,we introduce the reinforcing scheme and the construction technique in detail as well as the construction process after analyzing the reasons of the disable bridge.

Fuzzy decision of one reinforcing plan;

Aiming at the main difficulties and risks of bridges and culverts on haven-built railways,combined with the field construction environment,the different line reinforcing plans were choosed and the different construction plans were compared analysis,so the best plan was obtained,which make the line reinforcing plan more scientific and reliable.

Alternative choice of strengthening scheme for one factory building in Taiyuan Iron and Steel Group;

On the supplementary measures and strengthening scheme of shield end well of a station in Nanjing city

The structural analysis was made for the two-way curved arch bridge of the south approach bridge of Nanjing Changjiang River Bridge after the arch bridge was hit by fire and the bridge was later strengthened by the two-stage strengthening schemes.
