vibration compaction
2.Based on the routine test of rockfill, built indoor model experiment of it under the process of vibration compaction, the flat panel vibration machine was used to vibrate and compact the layered rockfill, the level instrument was used to observe the settlement of rockfill after vibration compaction, dynamical soil manometer was used to observe the pressure variety in the rockfill layer.
3.Experimental Study on Relationship Between the Vibration Parameters of Compaction Table and Sand Fluidity,Filling ?Compaction Densities for the Expendable Pattern Casting Process (EPC).
4.Concerned with compaction property of the Eolian Sand, in this paper the compaction technology and method of the Eolian Sand roadbed, from the pressure, vibration acceleration, working speed, depth of the Eolian Sand layer and compaction number is analyzed.
6.This paper expounds the harms and inf luences of strengthening the foundation with dynamic compaction on adjacent buildings,analyses the me chanism and regulation of the harms a nd influences caused by reaction spectrum of dynamic compaction vibration,and p uts forward the applying scope of dyn amic compaction and some vibrating i solation measures should be taken.
7.Technology of RCC is important progress of concrete construction technology and chaotic vibratory roller is of the modern technology. Based on the wide band vibration of the CVR made in Shanghai and Xuzhou, the author analyzed compaction mechanism of CV and the new technology of CVRCC, i.e. CVRCC is advocated in this paper. ?
8.According to the theory of structure vibration and the interaction mechanism of the system constituted by vibrating compactor and gravel soils, the theoretic warranty of dynamic monitoring for vibrating compaction is studied, and a data collecting system of the dynamic monitoring suited to the monitoring apparatus with acceleration transducers is established.
