摘要:
通过工程实例对强夯地基时振动加速度进行测试,分析了振动加速度的传播规律,提出建筑物安全距离判别方法及估算方法,研究了隔振沟的隔振效果及其对振动传播规律的影响.采用量纲分析原理,探讨了振动加速度与夯击能量、土的特性及传播距离之间的关系,通过大量的试验数据统计,得到经验公式和经验参数,由此可作为强夯加固地基安全距离的估算方法.
Abstract:
Based on the results of the measurement of the vibration acceleration during dynamic compaction, the rules of the transmission of vibration acceleration are analyzed. The rules to determine the safe distance between a building and the plot of dynamic compaction are suggested and the method to estimate the safe distance is built. It is studied how the ditch of isolating vibration eliminates the vibration due to dynamic compaction and affects the transmission of the vibration. Based on dimension principle, the relationships between vibration acceleration and the energy of dynamic compaction, the characters of the ground and the transmission distance are analyzed. The empirical formula is built by statistics analysis of the data from situ tests. It can be used to estimate the safe distance of improving the ground with dynamic compaction method.
