Semi-empirical methods SPT inputs for bearing capacity prediction

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.

本数据集为桩基承载力预测方法提供输入数据。所涉方法为四类经典半经验模型，用于预测单桩承载力。本数据集的数据采集自Lobo(2005)、Vianna(2000)与Jr.(1988)的研究成果，涵盖取自巴西多个地区的168组载荷试验与标准贯入试验（Standard Penetration Test，SPT）实测数据。Data.csv文件仅包含各方法所用的数值型数据；Data_with_soils.csv文件则包含对应桩基的土层类型信息。

后缀'Dq'、'Mey'、'Av'与'Tx'分别代表该输入对应的模型来源，依次对应Decourt与Quaresma(1978)、Meyerhof(1983)、Aoki与Velloso(1975)以及Teixeira(1996)提出的模型。

各列对应的含义如下：
N_pile：桩基编号（用于参考）；
SPT_L：桩身范围内的标准贯入试验（SPT）结果；
SPT_P：桩端处的标准贯入试验（SPT）结果；
Soil_L：桩身范围内的主要土层类型；
Soil_P：桩端处的主要土层类型；
L：桩长；
D：桩径；
Qu：依据NBR 6122标准载荷试验得到的单桩承载力。
