自改革开放以来,我国的基本建设发展迅速,大量的土地资源用来搞基本建设,所以现在征用土地越来越困难。不少单位采用在原建筑物上加层的方法来解决生产和生活用房问题。但是由于盲目加层造成了不少事故,这个教训不能不引起重视。 Since the reform and opening up, the country’s basic construction has developed rapidly and a large amount of land resources have been used for basic construction. Therefore, it is increasingly difficult to requisition land. Many units adopt the method of adding layers to the original building to solve the problem of production and living houses. However, due to blind incidents that caused many accidents, this lesson cannot be ignored.
