Long term creep pressuremeter tests in soft rock (St. Petersburg, Russia) Conference Paper uri icon

abstract

  • 2018 Taylor & Francis Group, London, UK. Pressuremeter test is used worldwide in geotechnical engineering particularly useful for the design of foundations. It consists of inflating a cylinder in a borehole. The expansion is typically done in equal pressure steps that last one minute. Special pressuremeter tests with up to 20 minutes long pressure steps were conducted for the foundation of a tall building on soft clay rock in St. Petersburg, Russia and are presented in this paper. The behavior of the soft clay rock under creep loading is modeled with a power law model. Recommendations are made to optimize the length of the PMT test while retaining much of the needed information.
