摘要

摘要: 通过对在黏土中静力压入等截面钢桩和3根不同侧壁倾角的楔形钢桩的室内模型对比试验,对静压楔形桩及等截面桩的挤土效应进行研究。通过试验,获得沉桩过程中地表隆起随沉桩深度变化的规律及最大隆起的位置和大小。最后对压入等截面桩与楔形桩的试验结果进行比较分析。

Abstract: Based on model tests of one equal section steel pile and three tapered steel piles with different side obliquity pressed into clay, the compacting effects of equal section pile and tapered pile in clay ground are studied. The laws of ground heave chang ing with depth during the process of static piling in clay, the location and the value of the max imal ground heave are obtained. The testing results of static piling equal section pile or tapered pile with different side obliquity are also compared and analyzed.
