[提要]  分析了用峰值加速度或峰值速度作為打樁地面震動(dòng)對(duì)房屋建筑安全影響的評(píng)估指標(biāo)所存在的問題；提出了用反應(yīng)譜法和位移法作為打樁震動(dòng)對(duì)房屋安全影響的評(píng)估方法。工程應(yīng)用表明，與現(xiàn)有評(píng)估方法比較，該方法更為科學(xué)、合理和適用。該法對(duì)于強(qiáng)夯、隧道爆破施工等引起的地面震動(dòng)對(duì)建筑物安全影響的評(píng)估也很適用。
[關(guān)鍵詞]  打樁震動(dòng) 房屋安全 評(píng)估方法

The existing problems are intiroduced in that the peaks of acceleration and velocity of ground Motion are used as the factors of effects of pile driving induced ground motion on buildings, and as new estimating methods, the ones of spectrum and deformation are proposed. Applying them to actual construction of pile driving shows that they are more scientific and practical, and also suitable to the estimation of effects of ground motion induced by dynamic consolidation and tunnel blasting.
Keywords:  pile driving vibration; surrounding building structure; safety; estimating method
