连续配筋混凝土板应用于岩溶及采用空区 ,其作用机理与常规连续配筋混凝土路面存在本质区别。引进三维有限元分析方法 ,确定路面板的基本设计参数 ,并将板内纵向钢筋采用双层布置形式 ,以保证岩溶及采空区路基的稳定性 ,解决了岩溶及采空区路基连续配筋混凝土板的设计方法问题 Continuous reinforced concrete slabs are used in karst and empty areas. The mechanism of action is different from conventional continuous reinforced concrete pavements. Three-dimensional finite element analysis method is introduced to determine the basic design parameters of pavement slab. The longitudinal reinforcement in the slab is arranged in double layers to ensure the stability of karst and gob-side entry and solve the problem of continuous reinforcement of subgrade in karst and gob area Design method of concrete slab
