| 1. | Subsidiary costs for insurance premiums, inspections and ground vibration control can add up considerable amounts . 保险费,检查和地层振动控制的辅助费用可增加相当可观的数额。 |
| 2. | On the other hand , heavy tamping is also a transient impact load that will produce strong ground vibration 同时,从加载角度考虑,强夯又是一种瞬时冲击荷载,作用在地面时产生振动问题。 |
| 3. | To be provided with an appropriate softness , light weight , small grinding vibration , and excellent grinding operation with ease comfort 具有适当之柔软性,质轻,研磨震动小,加工作业舒适性佳。 |
| 4. | Ground vibration response laws are obtained in environment background vibrations , ground traffic and metro train 通过对测试结果的分析,得出了环境背景振动、公交车等地面车辆和地铁的地面振动响应规律。 |
| 5. | The attenuation of the ground vibration is closely relative to the physical and mechanical properties of the ground media 地面振动随着远离振源而产生衰减。衰减的程度与强夯作用场地介质的物理、力学性质密切相关。 |
| 6. | 2 . taking account of the direct effect of ground vibration on buildings , the ground responses caused by the moving loads is studied in detail 2 、考虑到地基振动对建筑物产生的直接影响,本文对移动荷载引起的地基响应作了详细的研究。 |
