有机废弃物填埋场自然坝体消险加固方案研究

Study on Reinforcement Scheme for Natural Dam of Organic Waste Landfill Site

摘要:

某有机废弃物填埋场封场之前存在岩溶和滑坡、崩塌等地质灾害，通过对场地条件和地质条件进行分析，对边坡稳定性进行计算，提出边坡加固方案，对于不稳定、欠稳定的楔形体区域采用框架梁+锚杆的支护，对于边坡整体稳定性较好的区域釆用喷锚支护，确保填埋场封场后坡体自身安全并提高其抗渗能力。

Abstract:

There are geological disasters such as karst, landslide and collapse before the closure of organic waste landfill site. Through the analysis of site conditions and geological conditions, the slope stability is calculated and the slope reinforcement scheme is proposed. For the unstable and understable wedge areas, the supports of frame beam and pin rod are adopted. For the overall stability of better slope areas, the combined bolting and shotcrete is adopted to ensure the safety of the slope and improve its impervious capacity after the closure of the landfill site.
