摘要
通过对云南富广高速公路银厂连拱隧道施工过程的分析,并对比邻近在建连拱隧道的不同施工方法,分析了偏压连拱隧道在采用不同开挖顺序施工时各阶段围岩的应力、应变状况,得出了一些结论,为今后类似连拱隧道的施工提供了合理建议。
Based upon analysis of the construction process of Yinchang double-arch tunnel in Fu-Guang expressway of Yunnan and compared with construction method of adjacent double-arch tunnel under construction the stress and strain Status of surrounding rock under various excavation orders of double-arch tunnel with lateral pressure are analyzed. Some conclusions are obtained in order Izo provide references for similar works in the future.
