柱锤冲扩桩法是一种新型地基处理方法,结合多年的工程实践与理论研究,对其加固机理进行了深入系统的理论分析,重点研究了冲击荷载的作用、冲孔的侧向挤密作用、孔内强力夯实的作用以及填料冲扩的二次挤密效应等,为柱锤冲扩桩法地基处理技术的进一步推广及应用提供了有力的理论依据。
The column-hammer punch-and-expand pile method is a new type of foundation treatment method. Combining many years of engineering practice and theoretical research, it has carried out a systematic and theoretical analysis of its reinforcement mechanism, focusing on the role of impact loads and the lateral compaction of punching holes. The strong compaction effect of the hole, the secondary compaction effect of the filling and expansion of the filler, etc., provide a powerful theoretical basis for the further promotion and application of the foundation treatment technology of the column hammer.
