| Abstract: | 32-m simply-supported pre-stressed reinforced concrete beams are used for the Yanmiao Bridge and the Yanmiao Mega Bridge of the Wuhan-Guangzhou Passengers-oriented Line,with the mobile form used for their construction. To ensure the safe construction and the accuracy of their linearity,static load tests for and monitoring of the mobile form are performed. The results of the tests and monitoring show that in the state of work the different parts of the mobile form remain within the permissible elasticity lim... |
