| The Three gorges reservoir area has the unique geology, hydrology conditions.theoverhead vertical pier which was builted on it was very different.from the traditionalhigh-pile pier structure. This paper based on Jiangnan da port container terminalproject in WanZhou, For reliability analysis of the overhead vertical pier Which wasbuilded in Annual changes in backwater area of Three Gorges Reservoir Area. In hugewater fluctuation environment, we focused on the impact force to the influence ofreliability of pier Widget. The research results, which has a certain value, can providereferences for the construction of the dock. This paper mainly completed the followingresearch work:First, using ANSYS to calculates the static structures, Find that all the constructionmembers are small eccentric compression based on the bending moment effect.Preparing for reliability analysis below.Then, for reliability analysis of aerial vertical Terminal with PDS and Monte-Carlomethod,and Explore reliability index of various components under different condition.We also found that, compared with other variable loads, impact force made the greatestcontribution to the bending moment of pile foundation,and its influence on thereliability index is much larger than the other variable loads.As the reliability index ofPart the pile foundation is much higher than3.5of the specification requires. So it isnecessary for a deeper study of partial factor of impact force Either from the safety ofthe pier structure,or from the full utilization of resources.At last, in view of method of determining the partial factor,Assume that the impactforce obeyed different statistical parameters to study the partial coefficient.Getting thespecial partial coefficient of impact force to overhead vertical pier.I hope that theresearch results can provide references for the construction of the dock which will buildin Annual changes in backwater area of Three Gorges Reservoir Area in future. |
