【摘要】 打桩振动因其传播过程受到地质结构、地面环境和振动持时等条件影响,导致振动效应差别较大。探讨了打桩振动对建筑物影响的评价标准和评价方法,并结合工程实例,通过调查、分析打桩振动与建筑物破损的相关因素,根据实测场地各方向的振动效应,结合各相关影响因子建立场地的衰减规律,合理地评判了打桩振动影响范围。更多还原

【Abstract】 Because the spreading process of piling vibration is influenced by the geological structure,the ground environment and the vibration duration time and so on,which causes the effect of vibration to be big difference.This article has discussed the evaluation criteria and the assessment method for piling vibration affected to the buildings.Through investigating and analyzing the relevant factors of the piling vibration,the vibration damage of the buildings is illustrated by engineering examples,the attenuation rule of site is established according to the actual effect of vibration in various directions and at various distances,and each related influence factor.Finally the piling vibration influence scope is estimated reasonably.更多还原
