[提要]  通過(guò)一系列典型試驗(yàn)和理論分析，闡明在強(qiáng)夯工法加固地基時(shí)，試圖以加大夯擊能量無(wú)限制地提高影響深度是行不通的。在設(shè)計(jì)強(qiáng)夯加固地基工藝時(shí)，應(yīng)考慮到“極限影響范圍”的存在，而該影響范圍僅與夯錘底面的尺寸有關(guān)。最后介紹了用強(qiáng)夯法加固回填地基的實(shí)例。
[關(guān)鍵詞]  地基處理 強(qiáng)夯 影響深度 極限影響范圍

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 ramrning 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. lt 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 back-filling ground by the dynamic consolidation is introduced.
