Excavations and ground disturbances can cause settlements in adjacent structures. The placement of fill in embankments can also lead to subsidence of underlying soils if they are under-consolidated or are poorly compacted. The magnitude of settlement is an important factor to be determined in these cases as early detection of settlements can lead to the implementation of corrective actions to rectify the settlement.
Settlement monitoring under embankments are undertaken using settlement plates, which are installed at existing ground level under an embankment and are frequently monitored. This can provide an indication of the magnitude of settlement under the embankment loads. Settlement plates are a simple and effective but accurate method to ensure that settlements are tracked continuously before thresholds are reached. AG can undertake the installation of settlement plates for monitoring which can prevent the need for corrective measures and help inform the client when necessary.
