Abstract: With the purpose to develop a fast procedure of intervention for stabilising earth slopes, a new precast structure taking advantage of prefabrication, post-tensioning technique, highperformance concrete and steel fibres has been designed. The retaining structures is constituted of four framed precast panels and ten slabs used as external contrast to anchor cables. The paper describes the on site placement phases and the GPRS monitoring of the structure during the first six months. The on site behaviour of the whole retaining structure and the stress variation due to rain, snow, temperature and relative humidity has been monitored by means of fourteen loading cells used to measure the strand forces, forty-two vibrating wire transducers for the surface strains of three panels and of two plates, five optical fibre sensors installed to measure internal strains and several optical measures used to control the rigid movement of the structure during the placing and every month after the placing. The experience is part of a larger research project aimed at investigating the soil-structure interaction and improving the current techniques employed to stabilize ground slopes.
