Management of post-earthquake construction debris in Tehran Metropolitan

Abstract

Earthquakes can lead to different levels of damages and subsequently produce significant volume of debris. Management of such huge amount of debris needs special attention. Thus, it is vital to develop a comprehensive and cost-effective management plan. The present study was carried out to estimate post-earthquake debris volume in the 22 districts of Tehran under various earthquake scenarios [magnitudes of 5, 6.5, and 7.5 on the moment magnitude (M W ) scale]. Subsequently, required machineries and manpower and equipment for removal of debris were calculated. Finally, best practical methods for reduction and recycling were also examined. The shortest routes for transportation of post-earthquake to disposal sites were also proposed using network analysis. Results showed that about 83, 321 and 4802 million cubic meters of debris will be generated at 5, 6.5 and 7.5 M W , respectively. Disposal site of about 13 km 2 is marked within the area of study for the management of debris. Preparedness, emergency operations, rehabilitation and reconstruction are among the main activities that can reduce the earthquakeinduced damages.

A systematic review of recent developments in disaster waste management

“…buildings and trees) and characteristic of disaster waste (e.g. density of buildings/trees/population, tree height, location of buildings/forests and age of buildings), and then to use the inventory data, so as to estimate the waste volumes (Pham et al, 2014;Askarizadeh et al, 2017;Askarizadeh et al, 2016;Poudel et al, 2018;Thompson et al, 2011;Garcia-Torres et al, 2017). Such a method can be used not only to estimate the data of waste volumes in the aftermath of a disasters, but also to predict the potential waste generation in the period of pre-disaster (Tabata et al, 2016;Tabata et al, 2018).…”

Lessons learned from the Ezgeleh–Sarpol Zahab earthquake of November 2017: status of damage and disposal of disaster waste

“…Apart from the direct impact of the earthquake on the structures, it is presumed that the insufficient strength of the loose agricultural soil amplified the tremors in this area as a site effect. 12 Liquefaction was reported in the vicinity of this housing complex [1], though the evidence had disappeared by the time of the field investigation owing to rainfall. However, remnants of long fractures were observed in the ground just a few meters from the buildings ( Fig.…”

“…Scientists from various geographic regions including Turkey [9,10], Iran [11][12][13], and New Zealand [14][15][16] wastes from natural disasters, particularly earthquakes. They have emphasized the identification, classification, management, recycling, and disposal of disaster debris as a key factor for rapid recovery and reconstruction.…”
