Bearing Capacity and Settlement of Foundations Using the Menard Pressuremeter Test Results

摘要

Design of foundations can be performed using empirical Menard pressuremeter rules. Another trend of interpretation of these tests consists of identifying the rheological soil parameters using analytical or numerical methods. These parameters are then used to evaluate the bearing capacity and settlement of soil foundations using numerical software. This paper deals with the bearing capacity and settlement predictions of bored pile based on numerical interpretation of pressuremeter tests. A numerical program is developed to analyze these tests taking into account a non linear elastic model and an elastoplastic model based on the generalized elastoplastic Prager's model with the Von-Mises. Numerical calculations using FLAC software, taking into account the rheological parameters derived from this approach are performed in order to predict the behavior of a single bored pile subjected to an axial vertical load. The predictions are compared to the measured data.
