| 摘 要： | 隧道施工中经常遇到破碎围岩而发生塌方及掌子面涌出、坍塌的事故。一旦塌方灾害发生,不仅影响工程进度,而且影响施工企业形象;若处理不当,将遭受更大损失,如塌方频繁发生,或留下隐患。提出一种新型隧道防塌控制技术—"双曲拱"耦合支护技术,支护效果表明该技术可靠性强,能有效控制隧道顶板坍塌,具有很好的经济效益和社会效益。

| Abstract: | Often fractured surrounding rock in tunnel construction and face the collapse and gushing,collapse accident.Once the landslide disaster,not only the project,but construction corporate image;If not handled properly,will suffer more losses,such as landslides are frequent,hidden or left.Made a new tunnel collapse prevention control technologies-"double-curved arch" coupling supporting technology,supporting effect indicates that the technical reliability,can effectively control the tunnel roof collapsed,with good economic and social benefits. |
