Measurement of Static and Dynamic Soil Stress and Strain using In-ground Instrumentation
Publication: Dynamic Response and Soil Properties
Abstract
Little research has been done to understand the behavior of the soil during vibratory compaction and quality assurance and quality control (QA/QC) testing with light weight deflectometer (LWD) devices. A better understanding of the dynamic behavior of the soil in response to the loadings imparted by these devices will aid in the development of continuous compaction control (CCC) as well as the refinement and acceptance of rapid spot test devices such as the LWD. To this end, earth pressure cells (EPCs) and modified linear voltage displacement transducers (LVDTs) were installed between lifts of lightly plastic clay to measure in-situ stress and strain. With these sensors, the ground response was subsequently recorded during vibratory compaction. In addition, data was recorded during post compaction QA/QC testing with a prototype LWD device. The importance of EPC spacing, laboratory calibration, and field installation along with LVDT modification and field installation are discussed in detail. Preliminary vertical stress and strain results from a single layer study are presented.
