NEL, D T  and  HAARHOFF, J. The failure probability of welded steel pipelines in dolomitic areas. J. S. Afr. Inst. Civ. Eng. [online]. 2011, vol.53, n.1, pp. 9-21. ISSN 1021-2019.

This paper considers aspects related to the nature of dolomite, sinkholes, the risk classification of dolomitic land, as well as factors affecting the failure of pipelines in dolomitic areas. The information and data presented are used to derive equations that may be used to predict the probability of failure of steel pipelines in dolomitic areas subject to sinkhole formation. Consideration is also given to other factors that may influence the failure of pipelines in dolomitic areas.

Keywords : dolomitic; sinkholes; pipeline; failure; probability.
