混凝土拱坝或碾压混凝土拱坝 ,无论在施工期和运行期 ,温度荷载都是引起坝体开裂及裂缝扩展的重要原因。对坝体裂缝扩展的分析计算 ,用断裂力学的理论和方法较为适宜。文章提出了用 DL0 8P2程序计算在温度荷载作用下拱坝裂缝的断裂力学计算方法。并以实际工程算例说明了其应用。
Concrete arch dam or RCC arch dam, both in construction and operation period, the temperature load is the main reason that causes the dam cracking and the crack propagation. Analysis and calculation of the expansion of the dam, fracture mechanics theory and method is more appropriate. In this paper, the calculation method of fracture mechanics of arch dam under temperature load is proposed by DL0 8P2 program. The actual engineering example shows its application.
