RELIABILITY ANALYSIS OF ROCK MASS DEFORMATION IN TUNNEL EXCAVATION BASED ON GENETIC ALGORITHM

  • 摘要: 由于隧道的开挖,隧道围岩的初始应力状态将发生变化,围岩发生卸荷变形,并可能导致隧道的失稳。为了研究隧道开挖后围岩变形的可靠性,建立了隧道围岩变形可靠度指标计算模型,并用遗传算法进行求解。应用本文方法对一高速公路隧道围岩变形的可靠性进行分析。从结果可以看出,围岩的潜在破坏区域出现在拱顶和两侧拱肩区域,从这些区域的可靠度指标和破坏概率值可以看出,该隧道毛洞的拱顶下沉和拱肩收敛可靠度都满足不了规范的要求,要及时进行支护。
