摘要
对不良地质环境条件下成桩工艺选型进行分析。某工程地质条件复杂,存在大面积淤泥质粉质粘土层,部分区域为流砂,且基坑正下方为地铁隧道。根据地勘报告以及各机型的优劣程度来分析现场成桩工艺,相关研究成果可为类似工程提供借鉴。
The selection of pile forming technology under unfavorable geological environment is analyzed.The engineering geological conditions of a certain project are complex,there is a large area of muddy silty clay layer,some areas are quicksand,and the subway tunnel is directly below the foundation pit.According to the geological survey report and the advantages and disadvantages of each model,the site pile forming process is analyzed,and the relevant research results can provide reference for similar projects.
