Abstract
Earth pressure cells (EPC) are one of the crucial instruments in geotechnical field for obtaining soil pressure on various structures such as retaining walls and foundations. The most common and economical types of EPC are sensors which quantify the deflection of sensing diaphragms by means of strain gauges or hydraulic type connected to vibrating wire transducers. The present paper covers the literature related to various types of earth pressure cells and factors affecting their response. Calibration of EPCs is very important prior to its application, and thus, available calibration methods are discussed. The developments done in the area of EPCs are also covered, and recommendations are suggested for better utilization of EPC to obtain reliable measurements.
