Investigation of Construction Materials Resources to Use For hydraulic structures using Geotechnical survey along with regional geological data, case study: flood control project for South Pars Energy Zone in south of IRAN

Most construction materials required for construction projects directly or indirectly supplied from nature. In fact، the resources of construction materials are formed from geological formations or rock units or sediments caused by erosion them in nature. Thus to exploration of construction materials، not only the engineering characteristics and physical properties of geological formations which selected as the mining of construction materials can be estimated from geological data، but also can play an important roles in the region for recognition and determination of the regional resources potential. This paper is a summary of study of the exploration borrow materials resources to use for hydraulic structures in the coastal area of south of IRAN (flood control project for South Pars Energy Zone). In this study، the potentials for various materials have been identified using regional geological information such as lithology of rock units، the description each of them، the conditions of their formation and their depositional environments and the geological structures and phenomena which effect on them. The potentials of region were prioritizing using the above data and other parameters (such as volume، availability…). Also، this knowledge can help to determination of the sampling points and the selection of optimized materials with the lowest risk of considerable. Results this research shows that rock layers with the same litology belonging to different geological formations can have different properties due to various condition of formation. Thus، the regional geological data and geological engineering knowledge can help estimate the engineering characteristics and physical properties of geological formations and determine regional potentials، cost reduction and reduction of duration of studies at various stages of study of the construction materials.
