[提要] 在強夯施工過程中，地面振動對周圍環(huán)境的影響已是一個不容忽視的問題。借用彈性半空間理論中剛性基礎(chǔ)瞬態(tài)振動的位移解，提出了估算強夯地面振動豎向速度峰值的半經(jīng)驗公式。工程實例的實測數(shù)據(jù)驗證了半經(jīng)驗公式的可靠性，可為強夯振動環(huán)境效應(yīng)評價提供有益的參考。
[關(guān)鍵詞] 強夯 動力基礎(chǔ) 地面振動 環(huán)境效應(yīng)Vibration generated by dynamic compaction is often detrimental to the surrounding neighbourhood. Based on elastic half space theory for arigid dynamic machine foundation, a method for the maxlmum peak of vertical velocity of ground vibration caused by dynamic compaction is presented. Agreement is found with the result obtained in field tests. The method can be a useful reference for environmental impact evaluation.
