| Abstract: | Based on an example of 100 m main span PC continuous rigid frame bridge that using cantilever construction segments,some measures of the start element supported by temporary pipe and cable crane and lifting equipment are discussed in detail.The problems of imbalance torque in cantilever construction using traveling carriage and non-plank construction technologies of the start element and the structural system conversion is successful by use of water for weight provisional measures and T-lock closure. |
