Advanced standard operating procedures for survey of buildings and structures of metallurgical production

Abstract

This article presents modern methods for determination of the depth of various types of foundations at the metallurgical industry facilities. It was decided to use modern geophysical research methods, such as seismic exploration methods in order to solve the tasks for determination of depth of pile foundations and deep foundations under conditions of operating production metallurgical site. Geometric parameters of foundations can be measured using engineering seismic equipment, and three-component measurement data shall be processed by means of specific processing flow. The use of coherency procedures makes it possible to separate the dedicated phases of reflection from the foundation bottom in the wave pattern. Reproducibility of results of foundation bottom laying depth with actual depth was checked using engineering seismic recording systems by uncovering of foundation check pit-holes at the blast furnace complex facilities No. 7 of JSC EVRAZ NTMK. The measurement accuracy of pile foundations and spread foundations equal to 0.5 meters was achieved by means of seismic techniques as a result of the measurements conducted at the metallurgical production facilities. © Published under licence by IOP Publishing Ltd.
