dynamic response of underground structures has always been a topic of concern for designers and researchers. the behavior of these complicated systems under blast loading is affected by various factors and parametric studies are required to investigate their significance. the importance of soil density around the underground structure through which, the waves of explosion of a penetrator bomb i...

The seismic behaviour of underground structures is generally satisfactory compared to the above-ground ones. However, despite of the buried structure confinement, in recent strong seismic events some underground structure as tunnels, pipelines and tanks suffered high damage; for this reason, a strong effort is focused to evaluate the seismic vulnerability of these structure and to give codes in...

Due to its unique sensitivity to hydrogen protons, magnetic resonance sounding (MRS) is the only geophysical method that directly detects water and can provide nondestructive information on subsurface aquifer properties. The relationship between the surface MRS signal and the location and characteristics of aquifers using large-coil (typically 50-150 m) sensors has been discussed based on forwa...

Urban underground space is an important non-renewable resource, and its value has increased in recent decades. Economic change and development is the most fundamental motive of evolution of the urban space, it also affected urban underground spatial development in a large degree. The paper try to analysis the urban economic affection in mechanism of evolution of urban underground space. The onl...

The global energy shortage has revived the interest in hydroelectric power, but extreme geological condition always pose challenges to the construction of hydroelectric power stations with large underground caverns. To solve the problem of safe design of large underground caverns, a Chinese-style intelligent stability design, representing recent developments in Chinese techniques for the constr...

The dominant working structure of an underground mine is a set of interconnected tunnels which provides access to ore zones and haulage of ore from the designated ore zones to the mill. This set of interconnected tunnels forms a network. We describe a mathematical network model and the modelling features of our two software tools for designing underground mine layouts that minimise associated c...
