The upper reaches of the Yangtze River are characterized by a complex channel shape, numerous curved shoals, and significant variations in water level. The conditions for constructing the waterway are complex and changeable. In recent years, the Chinese government has increased investment in waterway construction in this area. However, the new cross-river bridges often face problems such as limited site selection, limited span and scale, a high risk of ship collision, and deteriorating navigation conditions. These issues have an irreversible impact on navigation development. Therefore, it is urgent to develop a technology to guarantee bridge navigation safety that is suitable for the complex waterway in the upper reaches of the Yangtze River. Based on the navigation conditions of complex bridges in the upper reaches of the Yangtze River, this paper proposes a safety evaluation system for full-cycle bridge navigation, analyzed in five stages: planning, design, construction, operation and demolition. This paper also proposes a key technical system for full-cycle bridge navigation safety, adapted to complex waterway bridges in mountainous areas in the upper reaches of the Yangtze River. This technology can provide guidance for navigating bridges over complex waterways in the upper reaches of the Yangtze River and is of practical significance.

长江上游河段具有河道形态复杂、弯急滩多、水位变幅大等特点,航道建设条件复杂多变。近年来国家加大了对长江上游航道建设的力度,但新建跨江大桥的工程往往面临着选址受限、跨度受限、规模受限、船撞风险高、通航条件恶化等问题,对航运的发展造成不可逆的影响,构建一套适合长江上游复杂航道的桥梁通航安全保障技术迫在眉睫。基于长江上游复杂桥梁通航条件,本文提出桥梁全周期通航安全评价体系,从规划、设计、建造、运维和拆除等五个阶段进行分析,提出适应长江上游山区复杂航道桥梁全周期通航安全保障关键技术体系。该技术可为长江上游航道复杂桥梁通航提供一定的指导,具有实际意义。

长江上游河段具有河道形态复杂、弯急滩多、水位变幅大等特点,航道建设条件复杂多变。近年来国家加大了对长江上游航道建设的力度,但新建跨江大桥的工程往往面临着选址受限、跨度受限、规模受限、船撞风险高、通航条件恶化等问题,对航运的发展造成不可逆的影响,构建一套适合长江上游复杂航道的桥梁通航安全保障技术迫在眉睫。基于长江上游复杂桥梁通航条件,本文提出桥梁全周期通航安全评价体系,从规划、设计、建造、运维和拆除等五个阶段进行分析,提出适应长江上游山区复杂航道桥梁全周期通航安全保障关键技术体系。该技术可为长江上游航道复杂桥梁通航提供一定的指导,具有实际意义。

The upper reaches of the Yangtze River are characterized by a complex channel shape, numerous curved shoals, and significant variations in water level. The conditions for constructing the waterway are complex and changeable. In recent years, the Chinese government has increased investment in waterway construction in this area. However, the new cross-river bridges often face problems such as limited site selection, limited span and scale, a high risk of ship collision, and deteriorating navigation conditions. These issues have an irreversible impact on navigation development. Therefore, it is urgent to develop a technology to guarantee bridge navigation safety that is suitable for the complex waterway in the upper reaches of the Yangtze River. Based on the navigation conditions of complex bridges in the upper reaches of the Yangtze River, this paper proposes a safety evaluation system for full-cycle bridge navigation, analyzed in five stages: planning, design, construction, operation and demolition. This paper also proposes a key technical system for full-cycle bridge navigation safety, adapted to complex waterway bridges in mountainous areas in the upper reaches of the Yangtze River. This technology can provide guidance for navigating bridges over complex waterways in the upper reaches of the Yangtze River and is of practical significance.
