摘要：

In order to give full play to the advantages of rock-filled concrete (RFC) arch dams, further simplify the construction and speed up the construction progress on the basis of canceling vibration/rolling compaction and cooling pipe,RFC arch dams without transverse joints and casted integrally have been constructed in Zunyi,Guizhou Province, where is a mild climate area. In this paper, the stress analysis and safety evaluation on Lyutang,Longdongwan,Shaqian and Fengguang RFC arch dams is conducted under different calculation conditions by the trial load method. The closure temperature of each arch,dead load,calculation material parameters are studied. Suggestions for the trial load method of the integral casting RFC arch dams are presented, i.e., the stresses of an arch dam shall be checked by the trial load method where the calculated closure temperature for each arch shall be estimated according to the actual casting temperature of the arch, the calculation material parameters could be selected referring to concrete arch dams,and the allowable stress could be set as 1.5 MPa ~ 2.0 MPa. The method can be applied to not only integrated RFC arch dams,but also integral casting RCC or masonry arch dams. © 2020, China Water Power Press. All right reserved.
