This paper is focused on soil subsidence of small extend and amplitude caused by tunnel boring or the collapse of underground cavities, whether natural or man-made. The impact of the movements of the ground on existing structures is generally dramatic. It is therefore necessary to accurately predict these movements (settlements and horizontal extension or compression displacements). Even though...

The vibration generated by railway traffic causes complaints not only about sensible vibration levels, but about significant noise levels in the building lying beside or above rail lines. Therefore numerical methods to predict the effect of train passbys are very important to possess and to develop. This paper presents a new numerical prediction method based on the Rayleigh radiation integral w...

Ground, as a body incised by natural and human actions (European Landscape Convention), carries “stories”, going beyond quantitative values. As in text, it holds the keys to understand what covers or hides. In its thickness, shelters “implicit projects”. Understanding complexity requires physical perceptual commitment, challenging space: dimensions gradually forgotten Environmental Sciences. “t...

A Wireless Underground Sensor Network (WUSN) is a network of wireless sensor devices in which all sensor devices are deployed completely underground (network sinks or any devices specifically for relay between sensors and a sink may be aboveground). These networks can be utilized to monitor the underground environment, especially soil conditions and aboveground events, such as the presence of p...

Wireless underground sensor networks (WUSNs) can enable many important applications such as intelligent agriculture, pipeline fault diagnosis, mine disaster rescue, concealed border patrol, crude oil exploration, among others. The key challenge to realize WUSNs is the wireless communication in underground environments. Most existing wireless communication systems utilize the dipole antenna to t...

The cadastral system provides land ownership information by registering and representing land boundaries on a map. The current cadastral system in Korea, however, focuses mainly on the management of 2D land-surface boundaries. It is not yet possible to provide efficient or reliable land administration, as this 2D system cannot support or manage land information on 3D properties (including archi...

Underground railway stations are known to have elevated particulate matter (PM) loads compared to ambient air. As these particles are derived from metal-rich sources and transition metals may pose a risk to health by virtue of their ability to catalyze generation of reactive oxygen species (ROS), their potential enrichment in underground environments is a source of concern. Compared to coarse (...

A wireless underground sensor network (WUSN) is defined as a network of wireless sensor devices in which all sensor devices are deployed completely underground (network sinks or any devices specifically for relay between sensors and a sink may be aboveground). In hybrid wireless underground sensor network (HWUSN), communication between nodes is implemented from underground-to-air or air-to-unde...

Abstract Sinkhole occurrences due to underground water mains operations have piqued people’s curiosity. Most research works were in relation geophysical practices discover the subsurface cavity. Very few can be found investigation of soil stability cavity shapes. The actual shape an and its transformation is difficult predict, though sinkhole failures are mostly circular on ground surface. This...
