预应力锚索抗滑桩间隔浇筑面植筋加固研究

Research on Reinforcement of Prestressed Anchored Anti-sliding Piles by Pouring Bar and Reinforcing Bar

以泉店煤矿滑坡治理工程项目为研究对象,对间隔浇筑面进行抗压强度试验与点荷载试验。同时对间隔浇筑面采取植筋加固措施后进行模拟分析,发现间隔浇筑面能够明显降低混凝土试件的抗压强度与极限荷载,间隔面凿毛处理有助于提高混凝土的抗压强度与极限荷载。间隔浇筑处植入钢筋之后局部拉应力过大问题得到有效解决,间隔浇筑面承受应力随着植入钢筋配筋率的增大而越小。

Taking the Quandian coal mine landslide control project as the research object. The compressive strength test and the point load test on the interval pouting surface were carried out. The simulation analysis shows that the interval pouting surface can significantly reduce the compressive strength and ultimate load of concrete specimens, and the chiseling of the spacers can help to improve the compressive strength and ultimate load of concrete. The placement of steel spacing after the placement of the local tensile stress is too large to effectively solve the problem of spacing pouring surface with the reinforcement rate of steel reinforcement increases.
