 One of the subjects of geotechnical engineering is soil bearing capacity, which is a function of the engineering properties of subsurface deposits and foundation characteristics. In this study, the results of 78 exploratory boreholes drilled in Mahshahr Special Economic Zone and Bandar-e-Imam were used to produce engineering geological maps with the aim of determining the soil bearing capacity in that area. The result from the boreholes shows that the sediment of the area is mainly clay and to a lesser extent silty clay and silty sand. After determining the soil classification, engineering parameters were determined based on laboratory test results. Then by using Hansen's formula and considering the allowable settlement of the foundation, bearing capacity was calculated for square foundation (1×1) and (2×2) meters, strip foundation with buried unit depth and a mat foundation (10×20) meters with buried depth one and two meters. By using the ArcGIS software, the load capacity map of the study area was produced and result shows that the allowable bearing capacity in this area varies between 0.40 to 0.98 (kg /cm2) and the northern area has higher load capacity than other area.

Sungun copper mine is located in the East Azerbaijan province, 45 km north of Varzaqan County. In this research, in order to zonation of potentially unstable areas, slope mass rating (SMR), kinematical analysis and analytic hierarchy process (AHP) methods by using of Dips 6.0, Expert Choice and ArcGIS softwares were accomplished. In the study by using Analytical Hierarchy Process method, the effective general criterias on the failure of rock slopes and extraction benches including structural geology, geomechanics, groundwater condition of joints, morphology and degree of alteration were selected and ranked by forming a pairwise comparison matrix. Then the sub-criterias and alternatives are wheighted by using of overall row wheight method on the basis of their importance. Finally, by integration of obtained data layers in the ArcGIS system, the studied mine area was zoned in low, medium and higth category in terms of failure potentially. According to the results, the western, southern, southeast and scattered parts of the north area of the studied mine specially in mining benchs are more likely to rock slope failurs, which is in good agreement with field observations. The results showed that there is a fairly good agreement between the results of the methods used in this research. But due to the fact that in the hierarchical analysis method, other criteria involved in the failure are considered, and the result is more reliable.
