| Abstract: | The paper introduces the closure option of Chaobaihe Bridge which is a prestressed concrete cable-stayed bridge with low pylon,three pylons and single cable plane.It also analyzes and calculates the influence degree of various temperature effects in the closure course of the bridge.It also gives the actual measurement data of the influence of temperature on the linearity of the main girder.At last,different measures are used for the construction of closure sectors of side and middle spans to counter the temperature influence. |
