Displacement Monitoring at Verrand High Reinforced Soil Structure

This chapter describes how the Verrand high reinforced soil structure (HRSS) was built within the construction standards for a new highway that was designed to connect the Monte Bianco tunnel with the city of Aosta, in the Italian Alps. The first aim of the structure was to provide a stabilizing weight at the toe of a steep and unstable slope, which forms the left bank of the Dora River. About 10 m above the top of the stabilizing embankment, a shaft foundation of 30 m high pier was placed and the pier is one of four supports of 60 m long bridge. Additional purposes of the HRSS were the disposal of materials that were extracted from nearby tunnel excavations and to provide access to construction fronts beyond the embankment. The slope is basically formed by a glacial till, which can be described as a silty sand matrix containing gravel and large boulders. The glacial till is overconsolidated and slightly cemented. Both effects vanish within the surficial part of the mass, so that the slope can be considered close to limit conditions and the water table daylights about 10 m above the toe of the slope.
