摘要:
地铁施工过程中地表沉降是衡量与检验地铁施工安全性的重要指标之一,基于诱因的沉降规律分析有助于科学合理的采取补救措施,有效降低地铁事故的发生概率。针对南京地铁某平行双线浅埋暗挖隧道间距与埋深均随里程变化的特点,运用控制变量法对施工过程中采集的监测数据对比分析,总结地表沉降规律。结果表明:当上覆土岩比超过0.20、隧道净深比β达到0.52(隧道埋深不变)以及拱顶位于土岩分界线以上3种情况下,地铁隧道地表沉降较大; 得出隧道掌子面开挖对地表沉降的大致影响范围及时间效应。
Abstract:
In the process of metro construction,ground surface settlement was one of the key factors influencing the metro construction safety.The analysis of subway tunnel subsidence regularity based on incentive could take remedial measures scientifically and reasonably,and effectively reduce the subway accident probability.Nanjing Metro was a parallel double line shallow-depth tunnel with space and buried depth varying with mileage.The monitoring data from the construction process were analyzed by using control variable method and the surface subsidence rule was summarized.Results showed that the subway tunnel surface subsidence was larger than empirical value in three cases when the soil and rock ratio in the overburden exceeded 0.20,the ratio of tunnel spacing and depth β was 0.52(the depth of tunnel was certain),and the vault located on the boundary of soil and rock.The scope and time effects on surface subsidence by the tunnel excavation were concluded.
