Investigating soil compaction using strain transducer

Integration Of An Extended Octagonal Ring Transducer And Soil Coulterometer For Identifying Soil Compaction

The soil coulterometer is an “on‐the‐go” electro‐mechanical system which collects impedance force data at multiple depths using an oscillating coulter. During the initial testing (summer 2006), only vertical soil impedance force data was collected using a pressure sensor. To improve the performance of the coulterometer, an extended octagonal ring transducer was integrated into the system to col...

Numerical study of soil dynamic compaction using ABAQUS model

One of the most important methods of soil compaction is dynamic compaction, which is one of the oldest and economical methods of soil improvement up to great depths. This method is applied due to its many benefits, including its economic procedure to correct many kinds of soil. One of the most important issues that affect soil improvement methods is being economic. The three main method...

Soil Compaction: Effects and Amelioration

Soil compaction was identified as the cause of ‘growth stunting disease’ in sultana grapes and ‘red death’ in cotton at the Lower Orange River and Vaalharts irrigation schemes. In an experiment growth stunting disease was eradicated completely and yields of sultanas increased substantially by deep cultivation, which eliminated compacted soil layers. Ripping increased the quality of tobacco, and...

Numerical simulation of dynamic soil compaction with vibratory compaction equipment

Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...
