【摘要】：基于混凝土结构双向板理论,建立钢混充填挡墙配筋力学模型,并推导出充填挡墙配筋数量与充填体强度及充填挡墙厚度的关系式。以金川二矿区为工程分析实例,采用控制变量法(CVM)研究充填体强度和充填挡墙厚度与充填挡墙配筋数量的变化规律。研究结果表明:在充填挡墙尺寸一定的前提下,充填挡墙的厚度随着充填体强度的增大呈线性增大;当充填挡墙尺寸和充填体强度一定的前提下,充填挡墙的配筋数量与充填挡墙的厚度呈二项式相关,当充填挡墙尺寸和充填挡墙厚度一定的前提下,充填挡墙的配筋数量与充填体强度呈线性相关。最终得到充填体强度与充填挡墙配筋数量的理论关系式。
[Abstract]:Based on the bidirectional slab theory of concrete structure, the reinforcement mechanical model of steel concrete filled retaining wall is established, and the relationship between the reinforcement quantity of filling retaining wall and the strength of filling body and the thickness of filling retaining wall is deduced. Taking Jinchuan No.2 mining area as an engineering example, the relationship between the reinforcement quantity of filling retaining wall and the thickness of filling retaining wall is derived. The variable variable method (CVM) is used to study the change of filling strength, thickness of filling retaining wall and reinforcement quantity of filling retaining wall. The results show that: under the premise of certain size of filling retaining wall, the change of filling strength and thickness of filling retaining wall and the number of reinforcement of filling retaining wall are studied. The thickness of the filling retaining wall increases linearly with the increase of the strength of the filling wall, and when the size of the filling retaining wall and the strength of the filling body are certain, the number of reinforcement of the filling retaining wall is binomial related to the thickness of the filling retaining wall. When the size of filling retaining wall and the thickness of filling retaining wall are certain, the reinforcement quantity of filling retaining wall is linearly related to the strength of filling body. Finally, the theoretical relationship between the strength of filling wall and the number of reinforcement of filling retaining wall is obtained.
