    Abstract

    Accurate measurement of the static and dynamic earth pressures acting on structures is critical to understanding the behavior of and the interaction between structures and soil. Different types of devices are commercially available to measure the soil-structure contact stress, and the advantages and limitations of some commonly used devices are summarized. A new, easily constructible, simple, and robust sensor assembly for measuring pressures at the soil-structure interface is introduced and discussed. The sensors are suitable for a variety of potential soil-structure contact situations, including static and dynamic load cases and linear and nonlinear soil behavior. One static and two dynamic experimental case studies serve as examples to describe the construction, installation, and deployment of the new sensors. The static and dynamic calibration procedure of pressure sensors with capacities of 144 kPa and 288 kPa are described. Recommendations for investigators to build and implement the sensor for individualized research applications are provided.
