摘　　要：基于北京市房山区某不稳定斜坡,通过对保护对象的需求、现场工程地质条件等的精细调查和分析,确定灾害隐患三处,分别为房后边坡欠稳定、公路路基塌空、院前挡墙垮塌。在充分考虑各处地形条件及住户需求的基础上,应用精细化设计理念,针对房后边坡采用重力式挡墙、截水沟进行治理,针对公路路基塌空采用两级重力式挡墙进行治理,针对院前既有挡墙垮塌采用桩板式挡墙进行治理。探讨总结边坡工程的精细化设计理念,提出“工程安全、施工便捷、造价经济、以人为本、环境友好”的边坡工程精细化设计准则。Based on an unstable slope in Fangshan district of Beijing,three hidden dangers were pointed out by precise investigation and analysis of requirements of protected object and engineering geological conditions.The hidden dangers were the unstable slope behind the house,the collapse of the roadbed and the collapse of the retaining wall in front of the yard.On the basis of taking the geological and topographical conditions and householders’requirements into consideration,precise design concept was applied.Gravity retaining wall and intercepting drain were used to control the slope behind the house.Two-stage gravity retaining walls were used to treat the collapse of the roadbed.Sheet pile wall was applied to prevent the collapse of the retaining wall in front of the yard.Precise design concept in prevention and treatment of slope was discussed and summarized.The principles of’project safety,convenient construction,economical cost,people-oriented and environment-friendly’were put forward.
