Abstract:

A laboratory model study and computer analysis were conducted to develop an understanding of the basic principles governing the process of earthmoving accomplished by applying a repetitive gas explosion to the soil. The results were desired for estimating the performance characteristics and design criteria for the device known as REDSOD Repetitive Explosion Device for Soil Displacement. This study was concurrent with prototype testing being conducted at Southwest Research Institute. A small model embodying the basic features of the device was tested in cohesive and granular soils in a specially constructed soil bin. The computer simulation of the RESOD device provided a means of evaluating the effect of the system parameters on the dynamic response of the mechanical device. The computer program was adapted to fit the observed dynamic characteristics of the experimental model. A comparison of estimated RESOD productivity with that of conventional methods of earthmoving indicated that both were of the same order of magnitude. Modified author abstract
