COMPRESSION OF PEAT UNDER EMBANKMENT LOADING

Peat and organic soil are commonly avoided as sites for highway construction. There are situations when this is not possible or economical, and the peat must be dealt with. If the organic accumulation is relatively shallow, excavation and replacement are feasible. However, for deeper deposits other alternatives, including the preloading technique discussed here, need to be considered. Preloading both strengthens the peat, so that it can safely carry the intended load, and achieves long-term compression in an accelerated period. Prediction of the settlement of peat under both the service load and the preload is important. Rheological parameters can be derived from field testing to allow use of a method that predicts settlements and controls duration of preload. A case study involving a highway compares results predicted by the method with actual measurements.
