摘　　要：混凝土矩形薄板不仅广泛应用于土木工程领域,而且广泛应用于诸如水利、石油化工、铁路、公路等诸多领域,本文根据近年来已获得的四边简支、四边固定、三边固定一边简支、一边固定三边简支、两邻边固定两邻边简支和两对边固定两对边简支矩形薄板在横向变温作用下的挠度和内力解析解,利用MATLAB软件编制程序得到了这类矩形薄板在横向变温作用下的挠度和内力计算系数用表,从而为以后工程结构中四边支承混凝土矩形薄板在热环境下的设计计算提供了理论依据。Concrete rectangular thin plate is not only broadly used in civil engineering but also broadly used in such fields as irrigation works, petroehemistry industry, railway, highroad, etc. In this paper, through the analytical solution about the deflection and internal force obtained from the rectangular plate of four simply supported edges ,four clamped edges, three clamped edges and one simply supported edge, one clamped edge and three simply supported edges, two adjacent clamped edges and two adjacent simply supported edges, two opposite clamped edges and two opposite simply supported edges under temperature disparity, and using MATIAB software, the deflection and internal force calculation coefficient tables are obtained about this kind of concrete rectangular thin plate under temperature disparity. And so a theory calculation base about concrete rectangular thin plate with four sides supported under temperature disparity is provided for engineering design.
