摘要
本文采用原型观测资料及三维有限元分析，对金坑拱坝运行期裂缝成因进行了较深入分析，认为空库加温降是导致坝体横缝表面开裂的主要原因．所得结果对类似工程有较大的参考价值．
he paper presents a causing analysis of dam crack during Operational period in terms ofprototype observational data and by using 3 - dimensional finite element method. The main reasoncausing surface crack near transverse jointS iS a sudden emptying Of reserroir in combination withlarge drop in temperature. Results are valuable for reference in dam engineering
