OBTAINING MODULI FROM CYCLIC PRESSUREMETER TESTS Academic Article uri icon

abstract

  • Conventionally, a first loading modulus and a limit pressure are obtained from a pressuremeter test curve. This article shows how much information on the soil modulus can be obtained from a pressuremeter test. Soil moduli vary with the strain level. The pressuremeter modulus is measured at a large strain level; it is shown how an unload reload cycle can be used together with the hyperbolic stress strain model to find a soil modulus at any strain level. Soil moduli vary With the level of stress confinement. It is shown how an unload-reload cycle can be used together with a power law to find the stress dependency of the soil modulus. Soil moduli vary with the number of unload reload cycles. One pressuremeter test with 100 unload-reload cycles is presented; it is shown how the modulus and the plastic strain vary with the number of cycles. ASCE.
