对于混凝土拱坝或碾压混凝土拱坝，无论是在施工期还是运行期，温度荷载都是引起坝体开裂或裂缝扩展的重要原因。本文采用了基于朱伯芳提出的温度荷载简化公式和线元断裂力学原理编制的DL08P2程序，并结合工程实例说明了该程序的应用。
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.
