摘要
从交叉学科的角度论述桥梁通航标准的确定原则和方法 ,包括桥位选择、通航水位、净空尺度、航道选线、河床演变、安全保障措施等 ,提出净空尺度计算原则和斜交桥梁净空宽度计算公式 ,为跨航道桥梁的通航净空尺度和技术要求论证提供参考 。
Based on intetrdiscipline,the settlement criteria and methods of bridge navigation standard are expounded, including bridge site choice, navigation water level, clearance dimension, channel plan, safety measure etc. The calculating criteria of clearance dimension and the method of analyzing and calculating oblique bridge clearance width are advanced, offering a reference for the study of crossing channel bridge navigation clearance dimension and technical specification.
