【Abstract】 We use two graded hoggin concrete to build arch dams in Yichun Prefecture.This method can assure the construction quality of masonry .The anti seepage of masonry relies on itself .We can abandon the water tight deck (or water tight core).This method can shorten the time limit for a project and save the investment of a project.At last,it can raise the elastic modulus of masonry.更多还原
