Composite stress structure for reinforcing roof of base concealed karst cave and construction method of composite stress structure
The invention relates to a composite stress structure for reinforcing a roof of a base concealed karst cave and a construction method of the composite stress structure. A composite stress structure for reinforcing a roof of a base concealed karst cave comprises a reinforced concrete slab, the reinforced concrete slab is located above a roof surrounding rock of the karst cave, the reinforced concrete slab is in rigid connection with the roof surrounding rock, and the two ends of the reinforced concrete slab are anchored and supported on complete bed rocks on the two sides of the karst cave. The roof surrounding rock of the karst cave and the reinforced concrete slab structure on the upper portion are rigidly connected together, the effects of coordinated deformation and common stress are achieved, the bearing capacity of the roof surrounding rock of the original karst cave is fully exerted, and the cost of engineering treatment measures is effectively reduced; according to the method, the form that the beam slab crosses the karst cave is adopted, an original karst cave drainage channel is fully reserved, pier columns do not need to be arranged in the karst cave, the influence of karst water scouring is avoided, and the whole-life-cycle structural safety of a bridge or a tunnel is guaranteed; the original ecological form of the karst cave is reserved, and the environment-friendly and economic requirements of engineering construction are met.
本发明涉及一种基底隐伏溶洞顶板加固的复合受力结构及其施工方法。一种基底隐伏溶洞顶板加固的复合受力结构，包括钢筋混凝土板，所述钢筋混凝土板位于溶洞的顶板围岩的上方，所述钢筋混凝土板与所述顶板围岩刚性连接，所述钢筋混凝土板两端锚固支撑于所述溶洞两侧的完整基岩。将溶洞的顶板围岩与上部的钢筋混凝土板结构刚性连接在一起，达到协调变形、共同受力效果，充分发挥了原有溶洞的顶板围岩的承载能力，有效降低工程处治措施费用；本发明采用梁板跨越溶洞形式，充分保留原有溶洞泄水通道且因无需在溶洞内设置墩柱，不受岩溶水冲刷影响，桥梁或隧道全寿命周期结构安全得到保证；且保留了溶洞原生态形式，符合工程建设环保经济要求。
