The pressuremeter test can be considered one of the most important in situ tests in geotechnical engineering projects. The pressuremeter consists of two main elements: a radially extendable cylindrical probe, which is placed inside the borehole at the desired test depth, and a monitoring unit, which remains on the ground surface. These two parts are connected by cables and hoses. Coarse grained alluvium layers are major subsurface layers in urban areas, such as Tehran, the capital of Iran. Prediction of the behavior of these layers in geotechnical engineering problems is very important. Based on this, and for better predicting the constitutive behavior of coarse grained alluvium with cementation, physical modeling has been undertaken. For this evaluation, we used the pressuremeter test (PMT) in a laboratory chamber designed and constructed for this purpose. In-situ tests play an important role in any geotechnical engineering investigation. This test is capable of properly estimating the geotechnical and deflection parameters of soil. These parameters are the elasticity modules (E), the shear modules (G), the in situ horizontal stress
