Research on Abutment Sliding Stability Partial Factors of Songta Arch Dam
摘要
Abstract
The safety factor of abutment sliding stability of Songta Arch Dam is respectively calculated by using the specifications of SL 282-2003 and DL/T 5346-2006 in the design of Dam. Because the rationality and correctness of the determination of partial factor values in arch dam design specification of DL/T 5346-2006 has always been doubted, the relative safety rate is proposed to be used to demonstrate the rationality and correctness of the determination of partial factor values. The results show that: (a) the values of shear strength parameters, partial factors and variation coefficients of rock used in the specification of DL/T 5346-2006 are correct and reasonable; (b) the safety factors calculated by two specifications have same risk level; and (c) the safety level of abutment sliding stability of arch dam is slight lower when the allowed reliability indicator is valued as 4.2 for Class I structure with Class I security level.关键词
