Abstract: In the last few decades, tremendous progress has been made in the way of designing and implementing engineering structures. The main obstacle to the full realization of these ambitions is finding a suitable place where the desired structure can be placed with confidence. Therefore, "land" and "geological environment" have become the subject of civil engineering and geological studies. This research was conducted to create a relationship between the analysis of morphotectonic and geotechnical indicators to prepare a geotechnical zoning map of Iranshahr City, with an emphasis on the allowable bearing capacity of the foundation. Accordingly, the information on 26 boreholes related to projects inside the city was used. In these studies, the asymmetry ratio index of the drainage basin (Af), the sinuosity of the mountain front (Smf), the longitudinal slope of the river (SL), the width of the valley floor to its height (Vf), the hypsometric integral (Hi), the average slope index The axis of the channel (MASC) were calculated in different points of along the main faults of the study area. So, the results of these investigations indicate relatively active tectonics in the region. Furthermore, the mechanical properties of the soil were determined according to the results of direct shear, shear wave tests, and the SPT number, and then the bearing capacity was calculated for the strip foundation with a width of 2 and 1 meters and a depth of 1.5 and 1 meters and a map of the allowable bearing capacity of the foundation was prepared. The mentioned maps show that, in general, the allowable bearing capacity of the foundation in Iranshahr city, except for the northern and southern parts of the city, is high. Also, from the center to the southwest, with the decrease in the size of the particles and the increase in the percentage of natural soil moisture, the bearing capacity has decreased. Therefore, according to The relatively active tectonics of the region and the results of geotechnical parameters and further changes in the soil texture in different parts should be considered as necessary measures in the design of foundations for future structures and retrofitting in the current structure by performing deeper and wider geotechnical operations to increase the safety factor.
