| 摘 要： | 强夯处理地基技术是一种有效的地基处理方法,但由于其施工时的噪音、振动等对周围建筑物和环境的影响而限制了它的应用。强夯处理的对象（即地基土）非常复杂,不可能建立对各类地基土均适合的具有普遍意义的理论。文中利用曹妃甸工业区的强夯工程实例,对强夯振动在沿海吹填地基中的衰减规律及隔振沟的设置进行了探究,提出了加速度的衰减经验公式,并提出隔振沟的合理布置方案。该成果对强夯法在吹填地基中的应用具有重要意义。

| Abstract: | Dynamic compaction is an effective method in ground improvement.The application of this method is restricted because of its noise,vibration and construction environment.The object(be foundation soil)by dynamic compaction is very complex,so it is impossible for establishing an universal theory to suit for every kind of foundation soil.Attenuation characteristics of vibration and the influence of trench in hydraulic filling are studied by field detection in dynamic engineering of Caofeidian industrial park.Th... |
