Description

These datasets presents inputs for bearing capacity prediction methods. These methods are four well-known semi-empirical models for predicting bearing capacity of piles. The data was collected from the works of Lobo (2005), Vianna (2000) and Jr. (1988) and includes 168 load tests and SPT measures taken from severam Brazilian regions. . The file Data.csv is composed only with the numeric values used in each method and the file Data_with_soils.csv includes the soil types for the piles.

The suffix 'Dq', 'Mey', 'Av' and 'Tx' represents which method this input was obtained from, corresponding respectively to Decourt and Quaresma (1978), Meyerhof (1983), Aoki and Velloso (1975) and Teixeira (1996).

The columns indexes represents:

N_pile - Pile number (for reference);
SPT_L - SPT result for the pile lenght;
SPT_P - SPT result for the pile tip
Soil_L - Predominant soil type along the pile lenght;
Soil_P - Predominant soil type in the pile tip;
L - pile lenght;
D - pile diameter;
Qu - Pile bearing capacity, obtained through NBR 6122 load test.
