摘要
通过对重力式桥台裂缝成因的分析 ,提出温度裂缝是重力式桥台裂缝控制的关键 ,并分析了温度裂缝的两种不同类型及受力机理 ,还推导出两种不同类型温度应力的理论计算公式 ,计算了某实际桥台的温度应力 .
By analyzing the cause of gravity abutment crevice formation, the idea is raised that temperature crevice is the key of controlling gravity abutment crevice. Two different types of temperature crevice and their force mechanism were analyzed and their calculating formula was deduced meanwhile. Calculating temperature stress of some existed abutments.
