摘要
结合实际工程,提出了双减振沟减振措施,通过确定安全允许振速、测试检测点振动主频率和振动速度等数据,分析单减振沟和双减振沟在减少强夯振动影响中的效果。分析结果表明,减振沟在强夯施工中的减振效果较好,双减振沟的减振效果远好于单减振沟,能使减振效果大幅提高。
Based on engineering practice,this paper proposed double vibration reduction trench measures.Vibration reduction effect of single vibration reduction trench and double vibration reduction trench is analyzed according to determination of allowed safe vibration velocity,main vibration frequency and vibration velocity.Analysis results show that vibration reduction trench has good effect,vibration reduction effect of double vibration reduction trench is better than single vibration reduction trench.
