Abstract:

The online rapid structural computing platform of arch dam is researched. First, structural analysis and back analysis computing methods are established based on improved genetic algorithm and finite element method. Then, arch dam structural analysis and back analysis computing tool is developed, and online rapid structural computing platform is built based on cloud computing server using Web integration technology. Finally, a high arch dam is taken as the example for structural analysis. It is proved that structural state of arch dam can be conveniently, quickly and accurately computed by online rapid structural computing platform, and evaluation, prediction as well as diagnosis of arch dam structural state can also be achieved. The computing platform is expected to be a decision making assistant tool for online dam safety monitoring system and dam safety management.
