Protection interventions excavation of tunnels by freezing.

»Posted in Articoli

EXPERIMENTAL ACTIVITIES IN THE TOWN HALL STATION METRO OF NAPLES The project of the so-called Low Line Treat of the Naples metro stations are planned 5. Almost always it comes to making excavations of considerable depth in loose soils when groundwater. For the realization of the galleries of the station is being applied the technique of freezing. In particular we expect to achieve along the contour of the cable a coating of frozen ground with the purpose of preventing flow of water into the excavation and possible instability of the forehead and around the tunnel. In Piazza Garibaldi have already been completed two of the four tunnels under the project of the Station. In the City Hall station was started freezing nitrogen to the first tunnel. In this note refers...

Monitoring and statistical analysis of the temperature variation in concrete

»Posted in Articoli

The temperature variations may influence the behavior of a structure causing loss of strength in the materials and the birth of thermal deformation contributions that are added to the contribution associated with the actual state of stress. The problem is particularly relevant in structures characterized by large horizontal: is the case of the floors of buildings seismically isolated, in which, for simplicity of dynamic behavior, it avoids the presence of joints. In the present work, starting from a database of approximately 30,000 temperature measurements from sensors embedded in the concrete cast for the realization of a great work conducted in Naples, we analyze the trend of thermal variations which may occur inside the structure in concrete due to the...

The settlement protoappenninico of Fuorigrotta

»Posted in Articoli

The site of Fuorigrotta (Line 6-Metro) refers to an allocation protoappenninico in ancient times not far from the coast (500-750 m). Despite not having found housing facilities, it is likely that the village is located a few tens of meters E, in an area densely urbanized today. The ceramic material is plentiful, and scraps of bronze are indicative of near furnaces. The sequences identified archaeological tephro-stratigraphic and geomorphological reconstruction of Fuorigrotta allowed a characterization of the dynamics of geomorphic area. The site represents the first evidence on the BM1 in the city of Naples where, so far, are proven steps Eneolithic, including employment in Via Terracina, a few hundred meters from Piazzale Tecchio Download the full article ...

Introduzione   Rilevare un’opera, un luogo urbano, un territorio, significa tentare di stringere da più punti la realtà “ricostruendola” per successive approssimazioni in un modello geometricamente misurabile e qualitativamente valutabile. La finalizzazione con­diziona il processo stesso di rile­vamento e quindi le scelte e i cri­teri che orientano l’iterazione di mirate scomposizioni e ricompo­sizioni della realtà. In ogni caso, il modello finale, virtuale e analo­go, si configura come un’inter­pretazione della complessità della realtà. Da sempre gli strumenti e le metodologie di rilevamento, sia semplici che complessi, si con­frontano con la dialettica tra campo dell’ottica e campo della geometria, tra percezione e misura. Sistemi...

Tecniche innovative per il rilievo e la modellazione del territorio

»Posted in Articoli

Lucio Amato – Tecno In Servizi di Ingegneria   Poter utilizzare modelli digitali tridimensionali che rappresentino fedelmente la forma, le caratteristiche morfologiche e gli elementi cromatici, è di fondamentale importanza in svariate applicazioni dell’ingegneria, della geologia, dell’architettura e dell’archeologia. Negli ultimi anni, le classiche tecniche di modellazione assistita e d’osservazione e rilievo del territorio, sono state affiancate dalla metodologia semi-automatica di rilievo, comunemente nota come 3D laser scanning o LIDAR (light detection and ranging). La tecnica LIDAR consente di acquisire per punti il modello digitale della superficie rilevata. In relazione al tipo di applicazione, l’impianto di acquisizione può essere...
