| 摘 要： | 强夯技术加固地基具有经济、快速、高效等特点,在地基处理工程中得到广泛使用,但施工中产生的振动对周边环境影响较大,容易造成居民纠纷现象。针对同一场地沙漠土的1 000,2 000,3 000 kN.m能级强夯分别进行了不同距离的振动监测,监测强夯施工引起地面振动不同方向的加速度、速度、位移、PVS(峰值合速度)等,并对不同距离监测的振动波形进行对比分析,给出实测曲线,得出沙漠土低能级强夯施工振动的衰减规律以及隔振措施。

| Abstract: | Dynamic compaction of Ground Improvement is significant,economic,easy to operate and convenient.It has been widely used in foundation treatment works.The vibration of dynamic compaction construction may easily give influence to the residents block.In this study,different distance vibration monitoring is carried out.Dynamic compaction includes energy level of 1 000,2 000,3 000 kN·m in same fields.The acceleration in different directions,speed,displacement,PVS of ground vibration caused by dynamic compaction is monitored.It is also compared the vibration waveform monitored from different distance.The paper shows a measured curve,puts forward a vibration transmission law of low-energy level dynamic compaction construction. |
