ABSTRACT
This chapter deals with the application in design of interpreted results from pressuremeter tests. Figure 7.1 shows the methods used to apply pressuremeter results to design. The direct method, in which the results of tests are used directly in design, was originally developed by Mtnard. It is a common way to use in-situ test results. For example, results of SPT tests are used to determine, directly, the bearing capacity of foundations (Terzaghi and Peck, 1948). The direct method, possibly the most widespread method of the application of pressuremeter tests in design, is based on the philosophy that the behaviour of full-scale foundations can be related to parameters obtained from empirical correlations supported by theory. It is important that the design parameters are obtained in a standard manner and it is for this reason that the Mtnard method is separately identified. In that method the probe, the installation and test procedure, and interpretation are all specified as discussed in previous chapters. The direct method has also been developed for use with SBP and PIP tests.
