偏压连拱隧道施工优化研究

结合有关工程实例,选取具有代表性和典型性的浅埋地形偏压覆土厚度,对不同坡度情况下偏压连拱隧道结构受力及围岩屈服破坏等进行施工步骤优化研究,可有效防止由于地形偏压而产生的结构偏压受力的不利情况,实现连拱隧道工程的优化施工.

Research on Construction Optimization of Bias Voltage Double-Arch Tunnel

Combined with engineering examples, this paper researches the optimization of construction steps about bias voltage continuous arch tunnel structure stress and surrounding rock FAILURE on different slope by selecting the representative and typical shallow topography unsymmetrical thickness of covering soil, which can effectively prevent the adverse circumstances about structure bias because of the terrain bias, and realize the optimization construction of double-arch tunnel engineering.
