（大連市建筑設計研究院 116021）[提要] 網(wǎng)殼對支撐結構產(chǎn)生很大的水平推力，其基礎設計是非常重要的。結合工程實例，通過在欠固結地基土的場地條件下，采用振沖碎石樁方法加固地基，設計了特殊的抗推基礎，滿足了上部結構的需要。經(jīng)過現(xiàn)場靜載試驗，驗證了設計中取用參數(shù)的可靠性。

Dynamlc-ramming gravel pile was used to reinforce foundations in undercomsolidated soil and a special foundation was designed against pushing in a project, which met the need of the upper structure. The situ dead-load experiment verifies that the parameter in designing is reliable.
Keywords: underconsolidated soil; pushing foundation; dynamlc-ramming gravel pile; static test; friction factor
