Abstract：
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 foundation 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.
