Excavation near or above existing shield tunnels often results in adverse impacts on tunnel stability. To ensure the serviceability of tunnels, this paper presents experimental and numerical studies with reference to a foundation pit case history excavated twin-tube soft soils. The tests were firstly applied study deformation characteristics structural response tunnels. Thereafter, an extensive...

Modeling pavement performance by combining field and experimental data The accurate prediction of pavement performance is important for efficient management of the surface transportation infrastructure. By reducing the error of the pavement deterioration prediction, agencies can obtain significant budget savings through timely intervention and accurate planning. The goal of this research was to...

This study examines the influence of impact-driven installation on subsequent horizontal monotonic response small-scale monopiles by using a large-beam geotechnical centrifuge at 100g. A special device including hammer was developed to install open-ended 50 mm in diameter an embedment depth 250 flight, and then apply lateral loading monopile head without stopping centrifuge. The global local re...

The ultra-high strength self-compacting concrete, UHSSCC is the new generation type of concrete with a compressive strength higher than 80MPa. The application of this type of concrete on the serviceability state in CFRP strengthened unbonded post-tensioned indeterminate I-beam is monitored and the results are compared theoretically using different standards. For this aim, full scale I-beam of 9...
