| Abstract: | In this dissertation, according to the stress characteristics of cable-stayed bridge, the test pointarranging scheme for the targeted key section of the beam is introduced. By comparing and researching the meas- ured and theoretical value of beam stress, the rule of beam stress during the whole construction is analyzed. The regularity of transverse beam stress distribution and the influence of temperature changing on the beam stress are also analyzed. |
