广州市西江引水工程北江段过河管道是目前国内设计管径最大、单管穿越距离最长的采用沉管施工方式的过河段管道。通过对管道穿越位置、管道埋深、穿越段管槽等进行相关的优化设计及选择,保证了工程主体施工的正常进行,工程相关设计及实施经验值得今后类似工程参考。 The river crossing of the Beijiang River section of the Xijiang River diversion project in Guangzhou City is currently the pipe with the largest diameter in the country and the longest crossing distance of the single pipe. Through the optimization of the design and selection of the cross-section of the pipeline, the buried depth of the pipeline and the passage of pipe sections, the construction of the main project is guaranteed. The relevant design and implementation experience of the project is worthy of reference for similar projects in the future.
