| Abstract: |
Sichuan Kahalo Jinsha River Bridge is a suspension bridge with a main span of 1030m, and the anchorages on both sides are gravity anchorages. In order to adapt to special terrain and geological conditions, anchorage of Sichuan bank pioneered the use of frame structure as the anchorage foundation. The soil and the frame structure jointly bear the vertical load and resist the horizontal component of the main cable to form a "frame soil" community and fully mobilize the role of the undisturbed soil. At the same time, the distributed grouting technology is used to strengthen the soil around the frame structure, so as to further improve the safety factor. This paper introduces the topography and geology of the anchorage position, compares and selects different anchorage foundation schemes, and explains in detail the design concept, structure size and construction technology of the frame foundation. |
