利用有限元方法研究溢流坝闸墩裂缝加固方案

Application of the Finite Element Method in Reinforcing Project for Sluice Piers of an Overflow Dam

用三维有限元法和瞬态温度场理论对丰满溢流坝闸墩裂缝的情况进行了应力分析,建立了计算模型,对6种可能的施工过程所涉及的预锚力对闸墩应力的影响进行了组合模拟计算和分析比较,给出了坝顶钻孔加压灌浆、同时对闸墩施加水平锚索的加固方案。

The finite element method and semi-steady temperature field theory have been applied to a stress overflow dam cracks in Fengman Power Factory. And the mathematic model has been built. The effects of cable on dam pier in 6 kinds of the possible construct processes were simulated and analysized. A feasible project is proposed, which a hole is drilled on the top of dam, cement is injected into the hole, and the anchor rope is applied to the overflow dam analysis of prestressed reinforcing prestressed
