摘要： 为解决中关铁矿充填挡墙工艺复杂、成本偏高的问题，通过理论分析、受力计算及经济对比，开展充填挡墙受力特性研究及厚度参数优化，探究单次充填料浆高度对挡墙的影响规律，并对比 2 种挡墙构筑工艺的经济性。结果表明：单次充填高度控制在 1.6 m，2 次充填间隔时间 ≥15 h 时，挡墙受力稳定，完全过墙后可连续充填；采用楔形计算法，分别按抗压强度、抗剪强度及抗渗透性条件计算挡墙厚度，取最大值，确定最优厚度为 0.6 m。成本分析显示，单个混凝土挡墙成本 6 402 元，砖混挡墙成本 5 104 元；采用砖混挡墙替代混凝土挡墙后，年节约成本 129.8 万元，经济效益显著，可为同类矿山提供技术参考。

Abstract: In order to solve the problems of complex process and high cost of filling retaining wall in Zhongguan Iron Mine，through theoretical analysis，stress calculation and economic comparison，the stress characteristics of filling retaining wall and the optimization of thickness parameters are carried out to explore the influence of single filling slurry height on retaining wall，and the economy of two retaining wall construction processes is compared. The results show that when the single filling height is controlled at 1.6 m and the interval between two fillings is above or equal 15 h，the retaining wall is stable，and it can be filled continuously after completely crossing the wall. The wedge calculation method is used to cal‐ culate the thickness of the retaining wall according to the compressive strength，shear strength and anti�permeability conditions，and the maximum value is taken to determine the optimal thickness of 0.6 m. The cost analysis shows that the cost of a single concrete retaining wall is 6 402 yuan，and the cost of a brick�concrete retaining wall is 5 104 yuan. After replacing the concrete retaining wall with the brick-concrete re‐ taining wall，the annual cost is saved by 1.298 million yuan，and the economic benefit is remarkable， which can provide technical reference for similar mines.
