| 摘 要： | 隧道开挖必然会使地表产生下沉和变形,从而对地表建筑物产生影响。应用随机介质理论,对桐油山连拱隧道开挖引起的地表移动与变形进行了分析,推导了简化计算的具体公式,根据中导洞开挖地表移动参数按比例法确定了整个连拱隧道的地表移动计算参数,据此分析预测了隧道开挖对地表建筑物的影响情况,计算结果对指导隧道的施工有一定的意义,也为其它同类结构的设计提供了参考。图9,表1,参9。

| Abstract: | When tunnel is excavated, settlement and deformation must be occurred on ground surface above tunnel, and the construction on ground surface must be influenced. By using stochastic medium theory, ground surface movement and deformation of tong youshan double-arch tunnel due to its excavation is calculated, the simplified calculate formulas are deduced, the calculated parameters of the whole tunnel are obtained by using scale method from the parameters of middle lead tunnel, and according these, the influence degree on construction on ground surface due to tunnel excavation is forecasted. The calculating result has some significance to instruct the tunnel construction. 9figs. , 1tab. , 9refs. |
