Abstract:
The paper will summarize the common shoring techniques used in British Columbia, mainly in the Lower Mainland (Vancouver area) for deep excavation and under seismic conditions. It will cover a wide range of technologies, from classical and simple excavations with shotcrete and anchors, with good soil conditions, to complex technologies such as jet-grouting, secant piles and DMM for more problematic areas.
Some especially challenging deep excavation case histories will also be presented.
Keywords: Excavation, shoring, shotcrete, anchors, jet grouting, secant piles, DMM.
