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。
In order to calculate the safety distance of dynamic compaction impact on the surrounding environment, based on the dimensional analysis theory, a dual-control parameter correction and estimation method is proposed. The critical vibration velocity and “Seismic Design Code of Buildings” prescribed in GB 67222-86 “Blasting Safety Code” , GBT17742-1999 “China Seismic Intensity Table” as the critical vibration acceleration of the dual control parameters, the two parameters were corrected and analyzed to get the best vibration speed control parameters in order to accurately define the impact of dynamic compaction vibration on the surrounding environment safety distance , Which can provide a reference for the optimization of the compaction construction scheme.
