摘要
利用三维有限元模型计算了大顶子山人字闸门的单根背拉杆的预应力,并对其他各背拉杆的应力、预应力进行了优化计算,据此对全部背拉杆上的预应力作了调整,使其达到验收规范的要求。
The prestress in one of the diagonal braces of the miter-gate of Dadingzishan Shiplock is computed with a 3-D FEM model.The stress and prestress in other diagonal braces are computed with an optimal calculation model.According to the computational results,the prestress in all the diagonal braces is adjusted to achieve the acceptance code.
