Abstract

During the rainy season of 1982, foundation distress was occurred at several recently completed and still incomplete structures of an important mine project located in the Peruvian Andes. When the tailings thickener was tested an unexpected settlement started, some cracking was observed in the slab, and the central pier settled and tilted. The nature of the distress suggested the failure occurred as the result of the combined effect of a long term seepage under the bearing foundation soil and due to its different degree of compaction. This paper presents the characteristics of these problems as both foundation and fill materials, the probably failure mechanisms and a discussion of geotechnical design criteria to solving them.

A Case of Singular Geotechnical Failure for Industrial Structures in the Peruvian Andes

During the rainy season of 1982, foundation distress was occurred at several recently completed and still incomplete structures of an important mine project located in the Peruvian Andes. When the tailings thickener was tested an unexpected settlement started, some cracking was observed in the slab, and the central pier settled and tilted. The nature of the distress suggested the failure occurred as the result of the combined effect of a long term seepage under the bearing foundation soil and due to its different degree of compaction. This paper presents the characteristics of these problems as both foundation and fill materials, the probably failure mechanisms and a discussion of geotechnical design criteria to solving them.
