[提要] 某停機坪位于濱海地區(qū)，場地下普遍分布有較厚的高含水量淤泥土層，其上又堆積了粘性土夾大塊石的人工雜填土層。采用強夯置換法對該場地大面積荷載下的軟土地基進行了處理，詳細介紹了工程的現場試驗，參數設計、施工，并用鉆孔和地質雷達等方法對強夯后的復合地基進行了檢驗。沉降觀測表明工程達到了預期目的，取得了良好的技術和經濟效益。
[關鍵詞] 強夯置換 地基處理 淤泥 復合地基An aircraft parks lies in a coastal region. There are deep silt stratification with high moister contents under the ground. The soft ground is treated with dynamic consolidation replacement.The test insitu, design of parameters and construction for this project are introduced in detail. The composite subgrade consolidated is inspected by drilling and geological radar. The settlement survey shows that the treatment for parks ground attains expected purpose.
