摘要:
针对隧洞侧边不同位置的中、小尺度溶洞对城门洞型水工隧洞围岩应力、变形、塑性区以及隧洞支护结构受力特征的影响,采用有限元数值模拟方法进行了系统地数值试验.在系统数值试验基础上,根据溶洞对隧洞围岩应力、塑性区和支护结构受力的影响特征,提出了溶洞影响范围划分图,将不同距离和尺寸的溶洞分为强影响溶洞、有影响溶洞和无影响溶洞等三个等级,为施工中对不同溶洞的处理提供了一定的技术支持,对我国岩溶区的隧道和地下工程建设的科学化和定量化必将起到一定的推动作用.
Abstract:
The karst caverns tunnel problems with tunnel side different position in middle and small size are studied by finite elements numerically with the influence of tunnel surrounding rock stress, displacement, plastic zone and characteristics of support structure force for tunnel with the popular shape type water construction tunnel. Based on the numerical experimentation, karst caverns influence sphere zone is divided into three level in different distance and size from the characteristics of karst caverns impact on tunnel surrounding rock stress, plastic zone and support structure force, including strong influence, influence and non-influence karst caverns, and it gives some technology support to different karst caverns treatment in construction and promotes scientifically and quantification ally the tunnel and underground construction in China karst cavern zones.
