TOWARDS THE PREDICTION OF SUBSIDENCE RISK UPON THE CHALK OUTCROP

Surface karst landforms such as solution pipes, swallow holes and dolines are well developed on the Cretaceous chalk outcrop in Britain. The local frequency of these solution features on the chalk can be as high as on any of the best developed karst areas on other British limestones. However, the overall frequency of solution features for major regions of the chalk outcrop is much lower. Solution pipes, swallow holes and dolines often represent an engineering hazard because of metastable conditions, which, if disturbed, can result in ground subsidence. The research described here is aimed at producing a model to predict areas of subsidence risk upon the chalk outcrop. Considerations for the prediction of subsidence risk are outlined with preliminary analysis for two areas. This paper was presented at the Annual Regional Meeting of the Engineering Group of the Geological Society held at Birmingham University, 13th-17th September 1982. (Author/TRRL)
