【摘要】 为计算强夯施工对周边环境影响的安全距离,基于量纲分析理论,提出双控制参数校正估算方法,采用GB 67222-86《爆破安全规程》中规定的临界振动速度和《构筑物抗震设计规范》、GBT17742-1999《中国地震烈度表》规定的临界振动加速度为双控制参数,对两参数进行校正分析,得到最佳振动速度控制参数,以此准确界定强夯施工振动对周边环境影响的安全距离,可为强夯施工方案的优化提供参考。更多还原

【Abstract】 To calculate the safety distance of the dynamic compaction,this study offers a method of dual control parameter adjustment estimation based on dimensional analysis.Using the critical vibration velocity in ’blasting safety regulations’(GB67222-86) and the critical acceleration in Code for design of earthquake-resistant of structural constructions and The Chinese seismic intensity scale as the dual control parameter,made a adjustment analysis to these two parameters to get a best vibration velocity controlling parameter,hereby to define the accurate safety distance.This method should be useful in providing parameters to the propose optimization of dynamic compaction.更多还原
