Abstract
Load-settlement characteristic (Q-s) of an axially loaded pile can be empirically determined from a static pile load test or on the basis of calculations using, e.g. transfer functions or numerical methods (FEM). The transfer functions method usually rely on empirical data, i.e. the function parameters are determined on the basis of numerous pile test results. Thus this method takes into account pile installation technology and is more reliable than FEM, where a proper simulation of the pile installation is yet to be achieved. Load-settlement characteristics are very useful for structural calculations of the pile foundation. However, Q-s characteristics refer to a single pile. Moreover, field load tests are usually performed on single piles and hardly ever on pile groups or even just several piles. And yet most foundations are supported by a larger number of piles (group of piles) and it is commonly known that the working conditions of a pile in a group are different than that of a single pile. The described problem is analyzed numerically and empirically using model tests. The results of comparative computations and model tests of CFA and SDP piles working individually and in a group of nine piles are presented and discussed. Some conclusions regarding Q-s characteristics of piles working in a group are formulated
