Abstract
The performance of two mat foundations is examined. The first case history includes a mat founded over generally granular terrace soils, underlain by a deep clay layer of medium compressibility. The second case history includes a mat over stiff preconsolidated clay. The mats are analyzed based on laboratory test and field pressuremeter data using the Winkler method. The particular approach taken in the analysis includes the determination of the modulus of subgrade reaction for the design using Vesic's method. Vesic (1968). This calculation was developed for pavements but is based on the theory of plates on elastic media which applies to the cases analyzed. The case histories are used to check the estimated settlements calculated from this procedure against measured values. The mat deflections were calculated using a finite element computer program. Bowles (1974). These calculated values were compared to readings made at individual columns of the building. The best fitting curves were used to back figure compressibility of the subsoil as represented by the subgrade modulus.

Settlement Observations on Two Mat Foundations
The performance of two mat foundations is examined. The first case history includes a mat founded over generally granular terrace soils, underlain by a deep clay layer of medium compressibility. The second case history includes a mat over stiff preconsolidated clay. The mats are analyzed based on laboratory test and field pressuremeter data using the Winkler method. The particular approach taken in the analysis includes the determination of the modulus of subgrade reaction for the design using Vesic's method. Vesic (1968).

The case histories are used to check the estimated settlements calculated from this procedure against measured values. The mat deflections were calculated using a finite element computer program.
