Soil-Building Interaction under Surface Horizontal Strain Induced by Underground Mining

Seismic Analysis of Building with Underground Stories Considering Soil Structure Interaction

Current building codes lack explicit recommendations on how to simulate the seismic performance of high-rise buildings with multiple underground stories. Designers are typically basing their analyses on subjective engineering judgment and experience. Recent researches shows that seismic response of buildings with basement walls is a complicated phenomenon. This paper studies the seismic behavio...

Dynamics of Building - Soil Interaction

In this study of the dynamics of building-soil interaction, the soil is modeled by a linear elastic half-space, and the building structure by an n-degree-of-freedom oscillator. Both earthquake response and steady-state response to sinusoidal excitation are examined. By assuming that the interaction system possesses n + 2 significant resonant frequencies, the response of the system is reduced to...

Monitoring underground coal mining - induced subsidence

Monitoring of mine subsidence by means of classical methods such as optical levelling or Global Positioning System (GPS) surveys can reveal deformations with sub-millimetre to subcentimetre precision for localised areas. However, to provide data on a reasonably dense two-dimensional (2D) benchmark grid are costly and time-consuming for all but the smallest areas. Moreover, a regular re-survey o...

Surface Water–groundwater Interaction in the Fractured Sandstone Aquifer Impacted by Mining-induced Subsidence: 2. Hydrogeochemistry

Water quality along the Waratah Rivulet in the Woronora Lake Catchment, New South Wales (NSW), Australia, has been monitored during the last three years by the Sydney Catchment Authority. Water quality data shows changes in chemical composition due to cracking of streambeds and rockbars, and diversion of surface water into subsurface routes in the Hawkesbury Sandstone aquifer. Water quality ups...
