Since there exists no national design code for the kind watergates, the traditional way is to apply the similar code used in Japan regardless the geographical difference. In accordance with the past experiences, there is no engineering design failure being observed. However, there hardly exists a study report that concerning if the design of gate is structurally adequate. The present report takes a gate that has been used in ZhongShan Pumping station. For the reason of comparison, the present study first checked the gate by the traditional design way that analyzes the individual components. In addition, the a 3D model for the gate was then established by using a computer software. The static analyses were followed once the model was completed by a commercial package, COSMOS-DesignSTAR. It has been found that the stresses obtained by the traditional way are somewhat more conservative than those of CAE. In addition to the static analyses, dynamic analysis was also performed by taking the condition under a typhoon into account. Special care has been focused on the stormy wave pressure acting upon the gate. The results showed that the effect of stormy waves becomes much smaller in case the hydraustatic head is large. However, the life and dynamic stresses are all within the safe region for the present example. In order to give an optimum design model, the sample watergate has been redesigned by reducing the cross-sectional areas of the structural members. The new gate structure was then checked by both static and dynamic analyses. It was found the new design still can meet the engineering safety requirement. Based on this study, the optimization design procedures are also provided for the future needs. Wenlung Li 黎文龍 2004 學位論文 ; thesis 85 zh-TW |
