摘要
柱锤冲扩桩法目前还处于在半理论和半经验状态,成孔和成桩工艺及地基固结效果直接受到土质条件的影响[1]。用该方法处理深度超过20米的杂填土地基的工程实例不多,本文结合工程实例,对该方法处理较深杂填土地基的现场试验进行了分析,并得出一些结论及建议。
piles thrusted-explanded in columnhammer is in semi-rational and half experience statment at present , the craft of pile and hole, the result of foundation consolidation are influenced by soil property condition directly [ 1 ]. The example of project dealed with the method , used in fill foundation over 20 meter-depth, is few , this paper , analyzing living test of fill foundation with more depth, presents example of project, and gets some conclusions and suggestions.
