摘要 为安全、合理地提出隧道近接下穿高铁施工加固方案,依托某矩形双线隧道近接下穿既有杭深线高铁工程,采用理论分析、数值模拟及现场监测等方法对双线矩形隧道三维影响分区及其应用进行研究,结果表明:(1) 基于推导的横向、纵向影响判别表达式,可以建立该双线矩形隧道近接下穿高铁施工三维影响分区模型;(2) 在强影响区采用人工挖孔桩+D型钢便梁加固措施,能有效控制路基及轨道沉降,使双线矩形隧道安全下穿既有高铁;(3) 采用优选加固方案后,现场监测数据与模拟计算结果基本一致,各项监测指标误差均符合规范控制标准,验证影响分区模型的合理性及加固措施的安全性。研究结果可为类似的双线隧道近接下穿工程施工提供参考。

Abstract:This study aims to propose a safe and reasonable reinforcement plan for the underpass construction of a high-speed rail by an adjacent dual-track rectangular tunnel,theoretical analysis,numerical simulation,and on-site monitoring methods were employed. Leveraging the underpassing of the Hangzhou—Shenzhen high-speed rail project by a specific dual-track rectangular tunnel,this study conducted research on the three-dimensional impact zoning and its application. The results demonstrate that:(1) Based on derived discriminative expressions for lateral and longitudinal impacts,a three-dimensional impact zoning model for the underpass construction of the dual-track rectangular tunnel adjacent to the high-speed rail can be established. (2) In areas of significant impact,employing reinforced measures such as manual bored piles and D-shaped steel beam bracings effectively controls roadbed and track settlements,ensuring the safe underpass of the dual-track rectangular tunnel beneath the existing high-speed rail. (3) After adopting the optimal reinforcement plan,on-site monitoring data closely aligned with simulated results,with errors in all monitoring indicators meeting specified control standards,thereby validating the rationality of the impact zoning model and the safety of the reinforcement measures. The research findings provide a reference for similar dual-track tunnel underpass construction projects.
