摘要
水泥土搅拌桩及排水板作为软土地基加固方法,能够有效地提高复合地基的性能,但是上覆吹填砂时搅拌桩参数及排水板对软基处理效果的影响研究仍然缺乏。建立不同桩径、不同桩距、不同排水方案情况下二维有限元路堤模型,通过有限元数值模拟定量研究桩距、桩径、排水板对吹填砂软土复合地基的影响规律,并与实测数据进行了对比分析。
Taking Binjiang Avenue in Pukou District of Nanjing City as the research object, a two-dimensional finite element embankment model with different pile diameters, pile spacing and drainage schemes is established. The influence of pile spacing, pile diameter and drainage plate on the composite foundation of dredged sand and soft soil is quantitatively studied by finite element numerical simulation, and compared with the measured data.
