Ground Improvement in Large Infrastructure Projects – Croatian Experience

In modern construction, the need for foundation of heavy structures and building infrastructure on weak soils, those with inadequate bearing capacity, has become increasingly common. The decision as to which foundation methodology is suitable for such situations depends on the systematic examination of a range of influencing factors ; the adequacy and quality of information, the number of alternatives available to choose from, as well as the use of appropriate models and techniques towards the selection of the optimal, most favourable, alternative. In the selection of a suitable ground improvement technology a number of factors must be taken into account, of which the following are most significant: ground improvement goal, namely the degree of increase in stiffness, load bearing capacity or permeability, suface, depth and total volume of the soil being improved, soil type and its mechanical characteristics, availability of materials for the improvement (sand, gravel, mix), ecological factors and local experience, turnaround time and, of course, expenses. The paper presents the Croatian experience in decision making, risk control, designing, executing and quality control of ground improvement.
