某工程混凝土板开裂原因和控制措施

Analysis and Finite Element Simulation of Concrete Slab Cracking

以某工程混凝土板开裂为例．对混凝土板开裂原因进行分析．指出混凝土收缩、板的自重变形和温度变化是产生裂缝的主要原因．并通过理论计算和有限元模拟对比分析．给出相应的控制和处理措施．为同类工程事故的处理提供借鉴。

Take example for concrete slab cracking of some engineering, it analysis the reasons of concrete slab cracking, it point out that shrinkage of concrete, deformation of concrete slab weight and temperature variation are the main reasons of concrete slab cracking, then it provides corresponding control and treatment measures by theoretical calculation and finite element simulation, it provide reference for the similar engineering accident.
