【摘要】 在目前的规范中,混凝土重力坝地震分析时是不须要考虑温度荷载的,但对于丹江口大坝加高工程,众多的研究及现场的监测数据表明,丹江口大坝新老混凝土结合面开裂主要是由于温度应力引起的。为更为详实地反映大坝的实际情况,在考虑温度荷载和新老混凝土结合面开裂状态的基础上,对丹江口大坝进行了非线性地震反应分析。更多还原

【Abstract】 By the present Chinese design codes,temperature load in seismic analysis of concrete gravity dam is not required.The studies and monitoring data of the Danjiangkou dam reinforcing project,however,indicate that temperature load caused cracking and opening of the joints between the old and new concrete layers.This paper presents an analysis of nonlinear dynamic response of this dam,focusing on the effect of temperature load on these joints.更多还原
