【Abstract】 According to the characteristics of the layered construction, multilaminate structural formation and the seepage properties of the RCG matrix, layer interfaces and lift joints, the theories and applications of different water pressure tests are studied in detail. The tests include the conventional water pressure test with one test interval, water pressure test with three test intervals and water pressure test with cross holes. Among the analytical and numerical methods, the propositions of the planar method with center source of seepage and the back analysis with the combination of FEM and accelerating genetic algorithm to the unsteady and saturated-unsaturated water-pressure-test seepage are specially included. Finally, the results from the applications of the theories and methods to the partial water pressure tests in the project of Jiangya RCC gravity dam are presented.更多还原
