采用三维有限单元法对奥地利Ｋｏｌｎｂｒｅｉｎ拱坝用冰冻法处理坝踵开裂区及防渗帷幕后再蓄水时的工作性态进行了研究．研究认为，当坝体及地基为线弹性材料，计及库水压力、拱坝自重和冰冻温度荷载．得出了人工冻结是该坝处理后再次蓄水时坝踵又发生新开裂的诱导因素的结论 A three-dimensional finite element method was used to study the working behavior of Kolnbrein Arch Dam in Austria when it was used to treat the dam heel cracking zone and seepage prevention curtain before impounding. The study shows that when the dam body and foundation are linear elastic materials, the pressure of reservoir and water, the self weight of arch dams and the temperature load of freezing are taken into account. It is concluded that artificial freezing is the inducing factor of new cracking occurring in the dam heel when the dam is recharged after treatment
