Abstract

To address the challenge of precision in existing earth pressure measurement techniques, this study introduces the use of rebar strain gauges. This novel approach utilizes the tensile forces in reinforcing bars to accurately determine the earth pressure on retaining structures. Employing a bespoke experimental framework, the investigation assesses earth pressure on retaining structures under various states, including stasis, non-limit, and active limit conditions. It also documents soil dynamic changes under non-limit states through imaging, with empirical data analyzed alongside theoretical forecasts. The results highlight that rebar strain gauges enhance measurement accuracy by ensuring a clear distinction between the sensor and soil, thus reducing errors from soil characteristics and sensor positioning. Compared to traditional methods, this approach significantly narrows the gap in earth pressure readings under static and limit conditions by factors of 2.23 and 2.49, respectively. This system promises to validate standard retaining structure designs and support the empirical and theoretical exploration of innovative retaining solutions, offering broad application potential.
