Seismic study of land subsidence and Vulnerability of Rural Buildings by using geophysics methods, near Shiraz city
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 7, Issue 11
Abstract
In recent years, land subsidence due to different reason such as excessive withdrawal of groundwater resources has lead to significant damages to farmlands, residential buildings, roads and transmission lines. Inattention to land subsidence results in the ruining of buildings which in turn causes the migration of people and imposes financial and social costs on the government and also changed the quality of ground water resources; increase Salinization of water, depletion of underground aquifers (the second largest fresh water source in the world) and creating fissures and sinkholes. However, some of the buildings in rural areas have lost utilization capability and their Habitation in Fars Province due to neglect of this phenomenon and propagation of cracks and gaps in the roof, Floors and walls. In this paper field observation was conducted and identified damaged villages in Marvdasht plain to investigate effects of faults and earthquakes on land subsidence and available gaps. And vulnerability index of these areas (vulnerability index of structures) was identified by using seismic method in the range of Shul village. And also soil status was determined by using Geoelectric method. Then, vulnerability status of damaged buildings was presented into future earthquakes and at the end of the research, suitable solutions were offered to prevent this phenomenon and its damages.
