珠三角某地下隧道矿山法施工技术条件分析

面对工程建设、环境与安全之间的平衡要求,大都市圈中地下隧道的矿山法施工,一直是工程建设的挑战,并无一劳永逸的解决方案。多洞同期矿山法施工,结构复杂且互相影响,工期紧张,安全及环境要求高,需要深入分析工程地质及水文地质条件、场地地基、不良地质作用、周边环境等,不断总结类似工程案例,以明确风险,优化施工技术方案。以珠三角在狭窄场地中三洞六线为对象,结合该区域地质条件及环境进行施工条件分析,提出有针对性的施工建议,以助类似工程的总结与提高。

In the face of the balance between engineering construction, environment and safety, the mining method of underground tunnel construction in metropolitan area has always been a challenge to engineering construction, and there is no solution once and for all. The construction of multi-hole simultaneous mining method has complex structure and mutual influence, tight construction period, high safety and environmental requirements, so it is necessary to deeply analyze engineering geological and hydrogeological conditions, site foundation, bad geological action, surrounding environment, etc., and constantly summarize similar engineering cases, in order to identify risks and optimize construction technical schemes. This takes the three tunnels and six lines in the narrow site of the Zhujiang Delta as the object, and combined with the regional geological conditions and environment, the construction conditions are analyzed, and the targeted construction suggestions are put forward to help the summary and improvement of similar projects.
