Abstract :
Digging of geotechnical boreholes and soil resistance tests are time-consuming and
expensive activities. Therefore selection of optimum number and suitable location of
boreholes can reduce cost of their drilling and soil resistance tests. In this research, a model
which is consisting of geo statistics model as an estimator and an optimized model is
selected. The kriging calculates the variance of the estimation error of different
combinations from available geotechnical boreholes. In each combination, n is number of
considered boreholes and N is number of available boreholes (N>n). At the end, the best
combination is selected by genetic algorithm (the error variance of this combination is
minimum). Also the Kean Shahr of Ahvaz city (in Khuzestan province, Iran) is selected as
case study in this research. Location of selected boreholes is in points that soil resistance of
these points represents mean soil resistance of total region. Optimum number of boreholes is
15. Also results show that location of selected boreholes depends to soil resistance and
diameter and length of applied piles are not important for this purpose.
