摘要
为深入了解国内密贴下穿地铁建设的研究进展,对目前国内主要密贴下穿工程进行汇总和文献调研,围绕工程特点、施工工法及沉降控制关键技术、变形内力影响规律和抗震分析几方面进行总结,找出了目前国内密贴下穿工程中存在的空白点和薄弱点.笔者认为现有研究在不同施工方法的适用性、工法的主要影响因素研究、施工步序的变形分配与受力转换、施工的沉降机理及抗震分析等几方面仍存在不足,并提出今后的研究方向,以期更好地指导工程实践.
In order to deeply understand the recent advances in closely-attached intersecting underground structures, the characteristic engineering, the most widely used construction method, the law of deformation and internal force and earthquake resistance were summarized respectively based on the summary of recent engineering and literature research. The advantages and disadvantages of each method were discussed and compared. The fact that further research topics mainly on the applicability of the different construction methods, the main factors that influence the method in construction, the steps of deformation distribution and force transformation in construction, the settlement mechanism and seismic analysis are still needed, was recognized, and suggestions for guidance for effective engineering were provided.
