ACOSTA GONZALEZ, Luis Enrique; RICARDO DESDIN, Sergio Edilio; CANO RICARDO, Yusleydis  e  RIVAS FREEMAN, Elizabeth. Geodesic monitoring of settling in vertical fuel tanks. Min. Geol. [online]. 2017, vol.33, n.3, pp. 265-277. ISSN 1993-8012.

The behavior of the settling in a vertical tank used for fuel storage was studied. Monitoring was conducted using the geodesic model for the geometric leveling of high accuracy category II. The original project varied during construction by replacing deep foundations with a surface one applying compaction techniques to improve soil resistance. The deformation values obtained provided valuable information on the implementation of the proposed foundation alternative depending on time and loads. The maximum settling was reported to be 132,6 mm. The displacements in the control points located in the perimeter of the tank had a distinct nature with a maximum of 44,2 mm, which caused the foundation structure to crack.
