Evaluación comparativa de los módulos dinámicos y resilientes de las arcillas del ex lago de Texcoco

Abstract

This research project consisted in the measurement of the dynamic modulus of elasticity (E) and resilient modulus (Mr) at different levels of effective stress (p ') by means of triaxial tests. With the obtained results, the previous modules were compared with the maximum dynamic elasticity modulus (Emax), measured with an alternative technique where a triaxial chamber with piezoelectric crystals is instrumented, which are used to induce and record cutting wave velocities (Vs) and compression (Vp). This was done for the BH-03 North soil sample, coming from the area where the New Airport of Mexico City is built. This research also compared the dynamic elasticity modulus (E) and the resilient modulus (Mr) for the PCA 3.2 and BH-03 North samples, measured with triaxial tests at different levels of effective stress (p '). From this comparison it was obtained that the relationship between both modules is linear and increase in constant proportion.
