| 摘 要： | 近年来土遗址受城市建设和交通施工损害的现象时有发生,对于这些人为因素对遗址的影响缺乏有效的检测与评估手段。本文基于G7高速公路的爆破振动观测,进行质点峰值加速度和峰值速度的衰减分析,开展爆破震动对附近明水军事要塞土遗址震动影响的研究。通过对竖向、水平向的振动加速度和速度的观测和数据分析,得出不同药量条件下,对应相同质点的震动峰值加速度衰减规律。提出了公路爆破附近土遗址震动控制范围和最大药量的施工建议,为爆破附近有土遗址的施工提供了数据支持,相应的结论和建议可以在同类土遗址保护中参考使用。 |

| Abstract: | In recent years, many earthen archeological sites have been extensively damaged because of urban and traffic construction as well as the lack of effective measures to test and evaluate them. Based on the blasting vibration observation of the G7 highway, the attenuation analysis of peak particle acceleration and peak velocity is carried out to study the impact of blasting vibration on the earthen archeological site of the Mingshui military fortress that is adjacent to the blasting site. According to the observation and data analysis of vibration acceleration and speed in vertical and horizontal directions, the attenuation law of vibration peak particle acceleration of some particles is examined under different explosive capacities. Construction suggestions related to vibration control site and maximum explosive capacity near the highway blasting are given, and the related data of blasting construction near the earthen ruins are accumulated. Finally, the corresponding results and suggestions can provide reference to similar efforts to protect earthen ruins in the future. |
| Keywords: | blasting vibration earthen archaeological sites peak acceleration peak velocity analysis |
