| Abstract: | 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. |
