Elkin V.A., 2018. Assessment of karst hazard in engineering surveys: a review of Russian regulatory technical documents. Engineering Survey, Vol. XII, No. 11-12, pp. 12-24, https://doi.org/10.25296/1997-8650-2018-12-11-12-12-24.
Engineering surveys are a required part of the construction activity in accordance with the Urban Planning Code of the Russian Federation No. 190-FZ of December 29, 2004 and the Technical Regulations on the Safety of Buildings and Structures No. 384-ФЗ of December 30, 2009. The analysis of domestic regulatory technical documents containing the terms, requirements for the composition, volume and methods of studying hazardous territories is presented. Requirements for engineering surveys in karst development areas are most fully set out in SP 11-105-97 (Part II); TCH 302-50-95 RB; TSN 22-308-98 NN; TSN 11-301-2004 Po, which are currently not valid. Issues of terminology are considered, problems in determining the normative indicators (sinkhole formation intensity and average diameter of karst sinkhole) are covered during the karst hazard assessment, in accordance with SP 11-105-97 (Part II). It is noted that it is necessary to make changes to a number of regulatory technical documents to eliminate contradictions and inconsistencies, especially in SP 22.13330.2016 “SNiP 2.02.01-83* Foundations of buildings and structures”, SP 116.13330.2012 “SNiP 22-02-2003 Engineering Protection of Territories, buildings and structures from hazardous geological processes. Fundamental principles”. The need to develop a new set of rules for the implementation of engineering surveys for construction on karst territories, in which it is supposed to take into account regional features of engineering surveys, is shown. It is proposed to take SP 11-105-97 (Part II) as a basis, in which the composition and volume of engineering and geological surveys are described in most detail and have not lost their relevance to the present.
