摘要

According to Dajing Station-Qilizhuang Station with the mining method Section close-range large-scale rainwater box drain subway tun-nel example along No. 04 Contract Section of No. 14 Beijing Subway construction,the paper illustrates a series of consolidation in caves adopted in the construction,and undertakes the crossing tunneling engineering by combining with the advanced geological forecast and supervision meas-ures,so as to provide some reference for similar projects.%通过北京地铁14号线土建施工04合同段大井站—七里庄站矿山法区间近距离下穿大型雨水方沟工程实例，详细阐述了施工中采取的一系列洞内加固措施，并结合超前地质预报及监控量测技术进行穿越施工，为今后类似工程积累经验并提供参考。
