In recent decades, the effects of blast loads on existing structures have gained considerable attention due to increase in threat from various activities. Site-specific empirical relationships for calculation blast-induced vibration parameters like Peak Particle Velocity (PPV), Acceleration (PPA), and Displacement (PPD) are commonly used estimation impact blasting an adjacent tunnel. However, th...

In this paper, the behaviour of pipe roof method with different roofs disposition schemes including gate system and L-shaped is discussed in terms ground settlement reduction condition underground space construction adjacent to existing structure by using numerical simulation method. Considering sequences parallel tunnels rectangular cross sections, appropriate parameters response characteristi...

A frequent problem when constructing metro tunnels is the uneven settlement of adjacent buildings, which results in huge economic losses. Due to shields causing this study took Nantong Metro Line 1 as research object. The runs from East Huancheng Road Station Intermediate People’s Court and passes under old residential area Community Sendadi-Huayuan building. Based on monitoring data, analyzed ...

This paper presents an original methodology for the rapid assessment of “potential” building damage caused by excavation. The combination Ground-work Impact (GI), in terms induced greenfield displacements, and Building Vulnerability (BV) form basis GIBV method. Both short- long-term displacements are considered impact evaluation. In addition to short-term displacement due undrained shear deform...

Buildings are the most important objects in urban areas. Thus, building detection using photogrammetry and remote sensing data as well as 3D model of buildings are very useful for many applications such as mobile navigation, tourism, and disaster management. In this paper, an approach has been proposed for detecting buildings by LiDAR data and aerial images, as well as reconstructing 3D model o...

The susceptibility of plants to burn raises concerns about fire hazard that green roofs may pose buildings. Main relate cases when such are poorly maintained or stressed by drought conditions which leads drying out and the accumulation dead organic material, greatly increasing availability fuel load. Existing standard safety measures aim prevent spread through vegetation cover. However, thermal...
