Design and practice of reinforced earth walls along the highway in the Croatian karst region

This paper presents a brief summary of the earth reinforcement technology, its applicability for various types of transportation projects and foundation soil conditions. Stressed is that use of this technology in addressing soil stabilization needs of transportation project can result in effective design solutions and achieve cost savings on large scale projects. The paper reports case study that illustrates the concept of design and construction issues related to this type of construction. Presented are design and practice of reinforced earth walls in karst region along the highway Split-Ploče. In the paper it is discussed that reinforced earth structures also serve for protection of environment, because they may play roll as storage for a great amount of crushed stone that is produced by cutting way through rocks. On the other hand, crushed stone is very suitable for this type of structures because of its high frictional resistance characteristics. In the paper, shortly is presented a stability calculation for the reinforced earth wall Strikići, the highest from until now built reinforced earth wall along the Split – Ploče highway. Special consideration is given to performance of reinforced earth walls during earthquakes. Finally, authors conclude that reinforced earth technology is a relatively straightforward and cost-effective construction process. Coupled with historically good performance under both static and seismic conditions makes earth reinforcement a valuable method in soil stabilization.
