摘　　要：垃圾填埋场土层具有土性成分复杂、厚度不均、土体结构复杂、力学性质差异大和高压缩性等特殊工程地质特点,对现场钻孔灌注桩施工极为不利。经工程地质分析和施工工艺分析研究,施工中采取了开挖施工基槽、砖渣铺垫、护筒护壁、黄土回填及混凝土超灌等处理措施,有效地保障了灌注桩的施工质量。The soil stratum of a landfill field has many special engineering geological characteristics, such as complex soil constituent, uneven thickness, complex stratum structure, different mechanical properties and high compressibility, producing great difficulties for field construction of bored pile. After analysis on engineering geology and construction technique, relevant measures, such as excavation of construction ioundation trench, brick rubble paving, casing breast wall, loess backfill and concrete overfilling, etc., are adopted during construction to effectively ensure the construction quality of filling pile.
