摘要
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。
For the concrete arch dam or the roller compacted concrete arch dam, the temperature load is always an important cause of dam cracking or crack propagating no matter it is in construction or in operation. And it is suitable to analyze dam crack propagating with fracture mechanics methods.This paper adopts the DL08P2 Program which is based on the simplified temperature loading formulas proposed by Zhu Bofang and linear element fracture mechanics principles, and its application is demonstrated with a practical engineering example.
