| 摘 要： | 根据西安地铁3号线通化门站—胡家庙站区间暗挖段工程特点,提出了台阶法+临时仰拱、中隔法(CD法)和交叉中隔法(CRD法)三种可行工法。运用FLAC数值模拟方法对三种工法引起的地表沉降进行了预测分析,确定台阶法+临时仰拱法为最优施工工法。实测结果表明,暗挖施工引起的地表沉降满足变形要求,提出的暗挖段施工工法合理有效。

| Abstract: | According to the characteristics of tunnel construction with deep excavated section on Xi'an metro Line 3,three methods are put forward:step method + temporary invert arch,CD method and CRD method.By using the FLAC numerical simulation to forecast the surface subsidence on the tunnel,the best construction method-step method + temporary invert arch is selected.The data of site monitoring indicate that the surface subsidence could meet the control standards,thus the construction method proves to be reasonable and effective. |
