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。
Dynamic compaction technology to reinforce the foundation has the characteristics of economy, rapidity and high efficiency. It is widely used in foundation treatment projects. However, the vibration generated during construction has a greater impact on the surrounding environment and is likely to cause residents’ disputes. Vibration monitoring at different distances of 1 000, 2 000, 3 000 kN.m level dynamic compaction in the same site of desert soil was carried out respectively. The acceleration, velocity, displacement, PVS Speed), etc. The vibration waveforms of different distance monitoring are compared and analyzed. The measured curves are given, and the attenuation law of the vibration of low-level dynamic compaction of desert soil and the vibration isolation measures are obtained.
