摘要
地铁等区间隧道两端多为强风化的岩层或残积土,中间较深段常遇到未风化或微风化的高强度岩层,单靠盾构法施工难以完成,多采用"矿山法+盾构法"施工。以深圳地铁某区间隧道为例,详细介绍了"矿山法+盾构法"工法中盾构在矿山法隧道内进出洞施工技术,提出了解决施工关键技术的措施,为这种新型复合工法的推广提供了良好的借鉴。
There are mostly serious weathered rocks or residual soils at the both ends of the regional tunnel,while the central deep-embedded range is filled with the fresh or slightly weathered solid rocks.The shield machine solely can＇t deal with this compound stratum.As a case of one tunnel in Shenzhen Metro,the technology of both break-out and break-in of shielded TBM in mined tunnel,some measures are proposed to solve the key technical problems.It is worth to use these composite methods for the future popularization and application for reference.
