| Abstract: | 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. |
