厦门市大嶝大桥过海段综合管廊规划研究及设计

摘要

随着我国综合管廊建设的逐步推广,必然存在综合管廊需要穿越河道、海湾的情况,然而此类工程难度大、造价高,且涉及部门众多.遇到此类情况时,常常只能断开综合管廊系统,采用常规管线挂桥或自行下穿水系的方式,这样从管线安全、维护管理、使用寿命、城市景观等方面都难以令人满意.城市综合管廊的系统性和完整性是发挥综合管廊成效的关键因素;海域使用论证、通航影响评价等相关问题研究是本工程顺利开展的保障;综合管廊的线路、工法选择、综合防灾及方案比选是综合管廊的设计重点,厦门市大嶝大桥过海段综合管廊工程的规划设计、相关研究及实践,为其他城市的综合管廊建设提供了参考借鉴.%With the gradual promotion of the construction of comprehensive corridor in China, it is inevitable that a comprehensive corridor needs to pass through a river or a bay.However,this kind of project is difficult,high cost,and involves many departments,and it is prohibitive. Through the evaluation of engineering conditions such as sea,navigation,geology and water pres-sure,the final decision is made by pipe jacking technology in this design project.According to the requirement of municipal pipeline,the comprehensive pipe gallery is divided into the municipal inte-grated cabin and the high voltage power cabin.The diameter of the cross section is 3 meters,and the length of the pipe jacking is 700 meters The system and the integrity of the city comprehensive corridor is a key factor to play a comprehensive pipe gallery effect,so that the comprehensive corri-dor planning for the over sea section of Xiamen Dadeng Bridge project provides useful reference for other city's comprehensive corridor construction.
