发明名称 Method for determining soil rigidity and soil compaction device
摘要 <p>The method of determining earth stiffness for an area of compressed earth uses a contact of an earth compressor applied to the surface. The contact face applies a periodically varying load to the earth surface with at least one frequency (f). The vibration frequency for the system is determined and the wave form used to control the compression force.</p>
