摘要
底轴驱动回转启闭式翻板钢闸门是近年来兴起的一种新型钢闸门,其闸室一般为单孔,跨度较大且结构复杂,如何准确把握结构各部分应力、应变分布情况至关重要。结合某闸室工程实例,就桩基条件下的ABAQUS模拟桩-土界面非连续接触行为和有限元网格划分原则进行了深入探讨,介绍了软土地基上此类闸室结构三维有限元计算的方法和思路,并对闸室结构应力进行分析,以指导工程实践。
The bottom shaft-driven flap-gate sluice has been widely used in engineering practice in recent years. Since the sluice chamber is generally single-span and the span is rather long,the accurate grasp of stress and strain distribution of each part is of great significance. The three-dimensional finite element calculation of the sluice chamber is systematically introduced combined with certain engineering project.Finally,the stress distribution of the sluice chamber is analyzed to guide the engineering practice,which is of great value for practice.
