摘　　要：为了解大型船厂工业地坪的实际力学性能与计算方法,通过对目前常用道路工程中多层弹性体系与土建弹性地基板两类模型的适用性进行分析,并结合船厂地坪特点,提出基于文克尔地基的多层弹性地基板模型,并对地坪分块名义刚度计算方法及地坪层间界面状态进行研究。计算结果表明:不同区域分块弹簧刚度设置起到了调节沉降变形曲线的作用,同时设置地坪层间滑动特性,地坪面层结构受力接近于板式构件受力状态。相关研究成果为制定相应设计计算方法及指导工程设计提供有益参考。In order to future understand the mechanical properties and calculation method of large shipyard industrial floor, the application analysis is conducted according to the road engineering multilayer elastic system and elastic foundation. According to the analysis result and mechanical property of floor, the improved multilayer elastic foundation model is put forward, which focuses on the floor block stiffness calculation method and interracial sliding between floor layers. The numerical simulation results show that different regional block stiffness can adjust the deformation curve; the mechanical performance of floor is close to the plate member by considering interracial sliding coefficient. The study described in this paper can provide a basis for simple, practical calculation method in future research.
