| 摘 要： | 研究内容是爆破振动在不同介质中的传播差异性。从理论角度对比研究了爆破振动在混凝土和软土中传播的主要特点及造成二者差异性的主要原因;指出混凝土介质中爆破振动速度主要分布在平面法线方向,软土介质中爆破振动速度主要分布在其平面上;并结合工程监测实践对分析结果作了进一步分析验证。本文结论对监测不同介质中的振动速度具有一定指导意义。 |

| Abstract: | Difference of blasting vibration in different mediums was researched.Main characteristic of blasting vibration in concrete and soft soil was contrastively studied in theory and main reason causing difference of blasting vibration in concrete and soft soil was also analyzed in theory.The results indicated that velocity of blasting vibration in concrete was mainly perpendicular to horizontal plane and velocity of blasting vibration in soft soil was mainly in horizontal plane.The conclusion was also confirmed ... |
