北京地铁暗挖区间隧道地表沉降控制方案研究

Study on the control of vertical displacement of ground surface over under ground cut tunnel of Beijing metro

结合具体工程的概况,分析了区间隧道施工对楼群的不利影响,采用有限元方法进行模拟,对可行的几种加固方案进行比较,从而选择出最优加固方案,以指导施工。

Combined with practical work the unfavorable influences of the construction of underground cut tunnel on surrounding buildings are analyzed, Based upon finite dement simulation several feasible strengthening schemes are compared.Optimal scheme is selected to instruct construction.
