高碾压混凝土拱坝真三维施工模拟

Three-dimentional Simulation of High Rol ler Compacted Concrete Arch Dam Construc tion

通过对高碾压混凝土拱坝施工过程的系统分析,将计算机数字模拟技术成功运用于高碾压混凝土拱坝施工管理与进度控制领域;采用深度缓冲区消隐技术对高碾压混凝土拱坝施工过程进行真三维仿真模拟。针对沙牌大坝施工进度严重滞后的情况,提出了特定情况下大坝混凝土的施工方案和工程措施,并进行了未来任意时段施工进度定量化预测。

This paper descri bes that through systimatic analysis of high roller compacted concrete arch dam construction procedures,computer mathema tic simulation technology is successfull y utilized in the construction managemen t and progress control.By use of depth b uffer region blanking technique,three-di mensional imitative simulation of high r oller compacted concrete arch dam constr uction procedure is realized.To counter that constrction of Shapai Arch Dam has lagged far behind the Schedule,through t he above simulation specific constructio n scheme of the dam concrete and enginee ring measures are put forward and constr uction progress for any future period c an also be predicted.
