摘要
通过一系列典型试验和理论分析,阐明在强夯工法加固地基时,试图以加大夯击能量无限制地提高影响深度是行不通的.在设计强夯加固地基工艺时,应考虑到“极限影响范围”的存在,而该影响范围仅与夯锤底面的尺寸有关.最后介绍了用强夯法加固回填地基的实例.
Through a series of typical tests and theoretical analyses, it is confirmed that it is unfeasible to ceaslessly increase the depth of influence when a soil foundation is reinforced with larger ramming energy. The existence of 'the ultimate scope of influence' should be taken into account when designing the process of reinforcing a ground by the dynamic consolidation. It also points out that'the ultimate scope of influence'is related only to the dimension of the bottom face of a pounder. Finally, an example of reinforcing a backfilling ground by the dynamic consolidation is introduced.
