TL;DR: In this article, a simple apparatus for laboratory calibration of diaphragm type earth pressure cells (EPCs) was designed and a new testing device was fabricated to permit the application of normal stress to the EPC using various types of soil and load configurations.
Abstract: The objective of this study was to design a simple apparatus for laboratory calibration of diaphragm type earth pressure cells (EPC). A new testing device was fabricated to permit the application of normal stress to the EPC using various types of soil and load configurations. With respect to fluid pressure, the response of the EPC can be different for the simplest earth pressure conditions because of an arching effect or nonuniform contact stress. For an EPC with a rigid outer rim, sensitivities computed from soil calibrations were lower than those determined from fluid calibrations by about 20 %.

TL;DR: In this paper, the evolution of shear zones in cohesionless sand for earth pressure problem of a retaining wall is experimentally investigated using a non-invasive method called particle image velocimetry.
Abstract: The evolution of shear zones in cohesionless sand for earth pressure problem of a retaining wall is experimentally investigated using a non-invasive method called particle image velocimetry. It is an optical technique for measuring surface displacements from successive digital images. Small scale laboratory tests are performed for active and passive cases of a rigid retaining wall subjected to horizontal translation, rotation about its toe and rotation about its top. Attention is focused on the effect of initial sand density on distribution of volumetric and deviatoric strain. The results for initially dense sand are qualitatively compared with corresponding ones obtained with X-rays at Cambridge University.
