2008年5.12汶川地震的阴霾还没有散尽,2013年4.20芦山地震又袭击了成都。4.20芦山地震发生后,成都特检院立即对全市电梯进行了大排查,成都有十几台电梯受损,受损的主要形式是对重架脱离导轨。5.12汶川地震后,成都市范围内大量电梯的对重架脱离导轨。对此,全国各地的检验机构做了大量的研究和分析,提出很多建议和要求,其中大多数建议增加对重架和导轨的强度。4.20芦山地震后,成都市电梯与5.12汶川地震相比受损率大大降低,电梯的破坏程度也减小很多。针对这一现象,笔者做以下几点分析,并提出建议。1 4.20芦山地震电梯事故率减少的原因分析
The haze of the 5.12 Wenchuan earthquake in 2008 has not yet cleared up. In 2013, the Lushan earthquake hit Chengdu again. 4.20 After the Lushan earthquake, Chengdu Special Procuratorate immediately carried out a large investigation of the city’s elevators, Chengdu, a dozen elevators damaged, the main form of damage to the heavy frame from the rail. 5.12 Wenchuan earthquake, a large number of Chengdu within the framework of the elevator from the rail. In response, inspection agencies across the country have done a great deal of research and analysis and put forward many suggestions and requirements, most of which suggest increasing the strength of heavy racks and rails. 4.20 After Lushan Earthquake, the damage rate of Chengdu Elevator compared with 5.12 Wenchuan Earthquake was greatly reduced, and the damage degree of the elevator also reduced a lot. In response to this phenomenon, I do the following analysis, and make recommendations. 1 4.20 Lushan earthquake elevator accident rate reduction analysis
