摘要:
［目的］中心城区地下综合管廊受地面实施条件与地下空间限制，可实施性差。对此，提出将综合管廊与地铁合建，实现同步规划、同步设计和同步实施，并探究综合管廊与地铁合建的不同型式。［方法］对管廊与地铁结合建设的必要性与建设原则进行研究。针对城市综合管廊与地铁合建型式进行分析。以广州中心城区地下综合管廊工程与广州地铁11号线合建项目为例，从用地节约、施工难度、协调要求等方面，分析不同结合型式的特点及适用情况。在结合各典型案例的具体情况讨论合建型式的适用性。［结果及结论］管廊与地铁相结合，同步规划、同步设计和同步实施，可以减少土地资源的占用，合理利用地下空间资源。共建共构是管廊与地铁结合建设宜优先采用的结合型式，可以大幅节省造价，最大程度地发挥合建的优点。管廊(井)与地铁主体和附属结构的结合方案的最终确定需因地制宜，结合现场实际情况综合确定。
Abstracts:
［Objective］ Due to the constraints of surface implementation conditions and underground space limitations, the implementation of underground utility tunnel in central urban area has poor feasibility. To address this issue, the concept of integrating the utility tunnel with metro system is proposed to achieve synchronized planning, design, and implementation, and to explore different modes of integrated utility tunnel and metro joint construction. ［Method］ The necessity and principles of utility tunnel and metro joint construction are studied, and the integrated construction of both is analyzed. Taking the joint construction project of Guangzhou central urban underground utility tunnel engineering and Guangzhou Metro Line 11 as example, the characteristics and applicability of different integration modes are analyzed from the perspective of land saving, construction difficulties, and coordination requirements. The applicability of joint construction modes is discussed based on typical cases and their practical implications. ［Result & Conclusion］ Integrating utility tunnel with metro system through synchronized planning, design and implementation can reduce land resource occupation and reasonably utilize underground space resources. Co-construction and co-structure are the preferred utility tunnel and metro joint construction modes, saving construction costs significantly and leveraging the benefits of joint construction to the maximum degree. The final determination of the integration scheme between the utility tunnel (shaft) and the main and ancillary structures of metro should be tailored to context-specific and comprehensive consideration based on actual site conditions.
