The development of vibratory plate compaction in North America, Japan and Europe is described. In Japan, the vibrator is attached to a massive plate and used as a bouncing tamper, operating at a low frequency. In Europe, the vibrator/plate system operates at a higher frequency and may be dynamically tuned by attaching a heavy mass, supported by elastomeric springs. Three case histories are presented where the compaction effect was carefully monitored by site investigations prior to and after treatment. These show that the depth of influence is directly related to the size of the plate. Finally, a recently developed application of the resonance compaction concept is described and illustrated by a case history.

振动板共振压实

描述了北美，日本和欧洲振动板压实的发展。在日本，振动器连接到一块巨大的板上，并用作弹跳篡改，以较低的频率运行。在欧洲，振动器/平板系统以较高的频率运行，并且可以通过附着由弹性体弹簧支撑的重物来动态调整。介绍了三个案例历史，其中在治疗前后通过现场调查仔细监测了压实效果。这些表明影响的深度与板的尺寸直接相关。最后，通过案例历史描述并说明了共振压实概念的最新开发应用。
