摘要
船闸底板常规施工方法对底板的工作状态不利,为改善底板的工作条件,提出了预留宽缝的施工方法.本文通过对原型观测资料的分析及非线性有限元方法的模拟计算,论证不同施工方法对船闸结构的底板工作状态影响较大,指出底板预留宽缝的施工方法是解决软土地基上船闸结构底板开裂的一种有效的方法.
The author has analyzed vast measurement data,and calculated the lock structure constructed by different methods with nonlinear finite-element method,pointed out the different construction methods have a great influence upon lock floor stucture on soft foundation,proved that the construction scheme of setting up construction joints in large floors is an effective way to prevent the thick lock floor on soft foundation from cracking.
