Geological studies and evaluation of the potential of Choghakhor region for the construction of a tourist village

Conducting geomechanical studies and examining the strength and type of soil before the construction of civil structures is one of the most important stages of studies in selecting the appropriate location for each geomechanical project. Geomechanical characteristics of soil are performed through surface and in-depth observations through borehole drilling, laboratory and on-site tests, and processing and interpretation of test results. In this research, the north of Choghakhor Lake has been studied in order to evaluate the potential of the region for the construction of a tourist village. In order to determine the type and thickness of soil and rock layers and to perform laboratory and on-site experiments, three boreholes were drilled. The test results show that the study site is located on young alluvial sediments of the mountainside, which is mainly a mixture of clay and silt with sand and some gravel. The depth of hand soil in the area varies from 0.5 to 1.5 meters and the level of the water table is located at a depth of more than 30 meters. Most of the standard penetration test values are observed at a depth of 6-8 m, which is due to the genesis and type of soil at a depth. According to Bell's proposed classification, more than 50% of the area's soil is in the hard category. According to the average values of adhesion and internal friction angle for drilled boreholes, the bearing capacity of strip foundation with a width of 1 to 4 meters, for three effective overhangs 1, 2 and 3 meters and length to width ratio of 1: 1 to 10: 1 it placed. The highest bearing capacity is P 2850 and the lowest is 1100 kPa. Changes in bed reaction coefficient, with changes in foundation width from 1 to 5 meters, are in the range of 34 to 286 kg / m3 and with an average value of 100 kg / m3. The range of acceptable changes in the bearing capacity of Pi, the location of most of the soil in the region in the resistant category, low water table, flatness of the study area and the consequent lack of landslide potential, indicate the high potential north of Choghakhor Lake to build a tourist village.
