陡立矿山岩壁治理中的飘台稳定性分析

Stability analysis of the floating platform in treatment of the steep rock walls in mines

摘要:

随着国家和社会的发展，人们对生态环境越发重视。在经济发展的过程中，因采矿而遗留下了大量的废弃矿坑，这些矿坑的治理迫在眉睫。飘台作为一种治理高陡光滑岩壁的有效方法，在实际工程中被大量使用，然而对飘台稳定性的分析大多停留在简单的公式上。本文设计了一种适用于陡立矿山岩壁治理的砼制飘台结构，提炼了计算飘台稳定性的公式并结合FLAC3D数值模拟软件，对飘台的稳定性进行了分析。研究结果表明，此砼制飘台比较适用于陡立矿山岩壁的治理。

Abstract:

With the development of the country and society, people pay more and more attention to the ecological environment. In the process of economic development, there are a large number of abandoned pits left by mining, and the treatment of these pits is urgent. As an effective method for treating high, steep and smooth rock walls, the floating platform is widely used in practice. However, most analysis of the stability of the platform is based on simple formula. In this paper, a kind of concrete floating platform structure suitable for the treatment of steep rock walls in mines is designed, and the formula for calculating the stability of the floating platform is refined, and the stability of the floating platform is analyzed by combining with FLAC3D numerical simulation software. The research results show that the concrete floating platform is more practical for the treatment of steep rock walls in mines.
