1Mechanical effects of excavation rebound of arch dam bedrock and better concreting time of dam body显示文摘In high ground stress zone, rebound deformation of excavation of arch dam bedrock has a significant impact on the structural behavior, design and construction of arch dam. Based on the analysis of mechanical effects of excavation rebound, with both stress and deformation as two constraint conditions and deformation modulus as a controlling condition, the method to determine a better concreting time of dam body was put forward. All of these play an important guiding role in the excavation of dam bedrock and the construction of dam body.WU ZhongRu GU YanChang SU HuaiZhi GUO HaiQing 2009Science China(Technological Sciences)2009,52,2:1
