Abstract: (1624 Views)
Background and Objective: Urban geology uses geological studies to manage risk of natural hazards and sustainable development in urban areas. In the circumstances that the geological hazards caused by the earthquake of November 12, 2017, had been sweeping the Sarpol-e-Zahab region, two underground tunnels were being excavated in the vicinity of the city. The negative effects of drilling operations of these two underground structures could intensify the crisis in the region.
Method: With the results of field visits and specialized texts review (articles, documents and reports), the geological hazards caused by the earthquake in Sarpol-e-Zahab region have been studied from the perspective of urban geological knowledge. Using the authors' executive experiences in the water transfer tunnels of Sarpol-e Zahab and Bazideraz, how to manage negative effects caused by drilling these underground structures (preventing the escalation of the crisis in the area) has been discussed.
Finding: The occurrence of earthquake has led to the occurrence of other geological hazards such as: "landslides, Rock Fall" and the region has experienced a pervasive crisis. In such circumstances, the tunneling operations intersected in places with surface water flows as well as with the city's transportation roads. The destructive effects of drilling operations of these tunnels could cause many problems (reduction of water resources, land subsidence and the problem of vehicle traffic on roads) and naturally the volume of problems of earthquake-stricken people increase.
Conclusion: The crises that occurred after the earthquake were directly and indirectly related to the geological characteristics of the city, so during the construction of tunnels, operational solutions tailored to the geological conditions were considered so that drilling machines safely cross high-risk areas and from the escalation of the social crises in the earthquake-stricken area be prevented.
