Dataset of measurements at an instrumented embankment on an outcrop of the Charmouth Mudstone Formation (Lias Group) in central England

Dataset of measurements at an instrumented embankment on an outcrop of the Charmouth Mudstone Formation (Lias Group) in central England. These measurements show ground deformations due to surface loading during the construction of an 8.2m high embankment in November and December 2020.
This dataset includes (i) downhole geophysical measurements of S-wave and P-wave velocity with depth at four locations, (ii) Extensometer measurements at two locations beneath the embankment (iii) Pressure cell measurements at two locations beneath the embankment. The measurement period ranges from the start to the end of construction of trial embankment in 2020.

Documentation

Data collection method:

These measurements were collected as part of a commercial ground investigation and embankment trial for the construction of the HS2 high-speed railway. The downhole geophysical measurements of P-wave and S-wave velocity were undertaken by a commercial contractor and extend to approximately 70 mbgl. The pressure cells and extensometers were installed by a specialist instrumentation contractor in advance of the construction of the embankment. They were logged at hourly intervals during construction of an 8.2m high embankment from November 2020 to December 2020. The data were used to produce Figures in the accompanying Journal paper. Please see the 'notes' files, which describe the Figures that each dataset relates to.
