三峡升船机上闸首结构动力试验研究及数值分析

DYNAMIC TEST RESEARCH AND NUMERICAL ANALYSIS FOR UPPER FLOODGATE HEAD STRUCTURE OF RISING SHIP MACHINE IN THREE STRAIT OF YANGTZE RIVER

采用振动台动力模型试验和有限元数值计算相结合的方法，对结构－岩基－库水系统的动力反应进行了分析，并应用于三峡升船机上闸首结构，结果表明：模型试验反映出的应力、变形规律是合理的，有限元计算的应力分布规律和试验基本一致，并且量值接近，这也说明了本文试验及计算成果的正确性与可靠性。

Combining the dynamic model test of vibration platform with the numerical calculation of limit element, the interaction of structure, rock base and reservior water system is analysed, and applied the result to upper floodgate head structure of rising ship machine in Three Strait. It is concluded that the stress and deformation law obtained from the model test is correct, the stress distribution from the limit element calculation is consistent with the test result.
