目前,当地基的承载力和稳定性不能满足建筑要求时,大型工业建筑多采用桩基,且桩数很多。因此,按正常基础施工的工期要求将不得不采取一面打桩、一面挖土、一面浇制混凝土的平行流水施工方法。为了解在打桩过程中,由于冲击引起的振动效应及其传播规律,影响范围、对作业造成的危害等,我们对某大型电厂进行了现场实测,分析了各种数据,并得出了安全距离和其它一些规律。 At present, when the bearing capacity and stability of the local foundation cannot meet the construction requirements, large-scale industrial buildings mostly use pile foundations and have many piles. Therefore, according to the construction period requirements for a normal foundation construction, a parallel flow construction method of piling, digging one side, pouring concrete one side has to be adopted. In order to understand the process of pile driving, due to the vibration effect caused by the impact and its propagation law, the scope of the impact, the hazards caused by the operation, we conducted a field survey of a large-scale power plant, analyzed various data, and obtained the safety distance. And some other laws.
