摘　　要：对于大跨径斜拉桥的施工,受各种不确定性风险因素影响大,技术要求较高,施工难度大。为保证施工的顺利进行,有必要对其进行施工期的风险控制。从桥梁具体的施工过程出发,通过风险识别、风险评估、风险应对三个步骤建立大跨度单索面公轨两用斜拉桥施工过程风险控制理论,并将其应用于重庆市渝中区千厮门大桥的施工风险控制。The construction of Large - span cable - stayed bridge is affected by uncertain ventures a lot, technically demanding, hard to construct. Therefore, it is necessary to control the risk of construction, so as to ensure the construction proceed smoothly. Starting from detail bridge construction, the theory of Large - span single plane highway and light -railway cable -stayed bridge construction risk is established though risk identification, risk evaluation and risk management, and this theory is used in the Chongqing city yuzhong district qiansimen bridge construction risk control.
