摘要
地铁区间隧道邻近既有建筑物,为保证既有结构的安全,对洞内注浆加固和隔离桩两种施工方案分析,采用数值模拟方法,通过对不同施工方案引起的既有结构沉降量比较,进而选择合理施工方案,以指导具体施工。实际施工监测成果表明,所选择的方案是合理的。
For existing buildings in the neighbouring of tunnel of subway between area and area, for the sake of ensuring safety of existing structure the analysis of construction plans for grouting reinforcement and isolation one is made, the contrast of settlements of existing structures bought above by different construction plan is performed, in addition the rational construction plan is selected to instruct specific construction. Results of monitoring the actual construction demonstrate selected plans are reasonable.
