By practice, the construction method of layer seam used to improve the layer stabilization can reduce the anti seepage criterion, simplify its construction process and bring down the investment of RCC dam to a certain degree.
实践表明,通过采用凹凸层缝施工法增强层面抗滑稳定,不仅能够在一定程度上降低坝体碾压混凝土防渗标准、简化工程施工以及降低工程造价,而且能够保证坝体的安全稳定。
In the paper the finite element method of three dimensional elastic theory is used to analysis the mechanice characteristic of cement concrete pavement consisting of tongue-and-groove joint under the vehicleload.
本文利用完全三维弹性理论有限元法,对以企口缝形式相连接的两块水泥混凝土路面板在行车荷载作用下的力学行为进行了分析,计算了在企口缝附近的应力状态和企口缝的传荷能力,得出了在行车荷载作用下企口缝的破坏形式,以及裂缝可能发生的位置,为合理布置接缝防止混凝土路面板纵向开裂提供了理论依据。
