摘要
以西安永利国际金融中心项目为例,分析了工程场地的地质条件,对工程采用的反循环钻机成孔泥浆护壁后压浆工艺进行了详细阐述,经实践指出:该工程应用超长灌注桩提高了单桩承载力,取得了良好的施工效果。
Taking the Xi＇ an Yongli international financial center project as an example, this paper analyzed the geological conditions of engineer- ing site, elaborated in detail the project used the reverse circulation drill hole slurry post grouting process, through the practice pointed out： the engineering application of super long bored pile to improve the bearing capacity of single pile, obtained good construction effect.
