1) collapse loads
坍方荷载
1.
Based on the analysis of the reason of the collapse in top area of a double-archde tunnel,FEM means is taken to study the bad effect of collapse loads and some other facotrs on the secondary lining,then some good advices are suggested for tunnel design and construct.
笔者在对一双连拱隧道洞顶坍方原因分析的基础上,借助有限元手段分析了此种坍方产生的坍方荷载等不利因素对隧道已施工的二次衬砌结构可能的各种不利影响,据此对连拱隧道的施工、设计等提出了一些有益的建议。
2) collapsible(sable) load
坍塌载荷
4) loading style
载荷方式
5) load direction
荷载方向

南场隧道软弱围岩段坍方分析及处理措施
2.
Construction scheme of tunnel passing through landslide area and fault zone;
穿越坍方区及断层带的隧洞检修洞施工方案
3.
But the condition of the surrounding rock is often poor,various and abundant with groundwater,so that the risk of the tunnel landslide and roof fall is great,and the possibility is also very large.
城市地铁常采用浅埋暗挖法施工,围岩情况普遍较差,变化多,地下水丰富,隧道坍方冒顶的风险很大,发生概率也大,如何在地表建筑物密集,交通繁忙的地段迅速处理好坍方事故,避免事态的进一步扩大,是设计和施工人员普遍关心的问题。
补充资料：坍方
路基、堤坝和河岸等边坡或山坡的坍塌现象。形成原因常为边坡过陡、土内水分增大、岩石风化及地震的影响等，和边坡或山坡的岩层构造也有关系。严重时可使交通中断或水流不畅。
