Abstract

vertical cracks may propagate through the whole dam under water pressure, which exist on the upstream of 18th section in Danjiangkou Dam. To solve the problems, stress intensity factor method of fracture mechanics is adopted, combing with three-dimensional finite element method. For different cracks treatment, propagation trend of old dam and new heightening dam is analyzed to give reference for designing reasonable treatment.
