Subways have been an important method for relieving traffic pressures in urban areas, but ground subsidence, during construction and operation, can be a serious problem as it may affect the safety of its operation and that of the surrounding buildings. Thus, conducting long-term ground deformation monitoring and modeling for subway networks are essential. Compared with traditional geodetic meth...

Three-dimensional model is established with finite difference method to simulate construction process based on design and construction plans of existing overpass pile foundation adjacent to certain large-section railway tunnel in Chengdu, China. Ground, isolation pile, main bridge pier and ramp pile near the tunnel are taken as research object, and surface settlement amount, displacement change...

Due to the scarcity of useable land in Hong Kong, it is a common practice to reclaim land from the sea. The reclaimed land usually undergoes a long period of settlement that may affect building structures and underground facilities such as water supply and sewage systems built on the land. Measurements of land settlement can provide valuable data for assessing the impacts of land settlement and...

due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. many models have been established for this purpose by extracting the relationship between the settlement a...

This study analyzes the solar potential on roofs of residential buildings in the city of Hamburg as a function of the city's settlement genetic characteristics. Hamburg's solar cadaster is critically evaluated with regard to rooftops, building, and settlement types as well as building orientation. Based on building ground plans, building and settlement types are calculated using geometric and g...

Ground surface settlement under subway tunnel construction is one of the main sources urban ground settlement, which may threaten safety existing buildings. Therefore, it necessary to study influence on and stability subsidence. In current study, originating from operation a tunnel-boring machine (TBM) while excavating double-line that underpasses buildings studied. To this end, numerical simul...

Shield tunneling construction of metro infrastructure will continuously disturb the soils. The ground surface will be subjected to uplift or subsidence due to the deep excavation and the extrusion and consolidation of the soils. Implementation of the simultaneous monitoring with the shield tunnel construction will provide an effective reference in controlling the shield driving, while how to de...

The last three decades have seen significant mining development in the northern regions of Canada, where the freeze and thaw cycle of permafrost and corresponding surface subsidence and heave represent a significant challenge at all mining stages, from the design of infrastructures to the monitoring of restored areas. Over the past ten years, SAR interferometry has been widely used to monitor g...
