简介:虽然钢筋混凝土的比重达2.5T/M3,其构件自重大,但当其形成薄壁水池构件时,在未灌水中空时,在特定环境下也会发生倾斜、漂移。1990年春节前,安徽省皖江机械厂两个400M3钢筋混凝土水池在施工过程中,由于拆模后未及时向池内灌水、池壁外回填土和池顶覆土,在外侧池塘渗透积水的浮力作用下,导致水池发生漂移,将池内立柱、底板与池壁连接处多处拉裂。一、两个400M3砼水池周围环境概况该蓄水池位于工厂生产区的东北隅,距东侧围墙约4米,围墙外侧有一面积约900M2深2米的水塘。工厂地下水位较低,约在自然地坪以下5M左右,两水池位于水泵房两侧,东西两厢布置,水池各为直径12.6M,高度3.5M的圆柱形钢筋混

简介:学校变革是教育改革的突破口与落脚点。大学与中小学在政府的支持保障或促成下进行合作的U-G-S模式具有重要意义,然而其局限也很明显:投入多、见效慢,理论研究者与实践者交流不畅。U-G-S-S模式承继了U-G-S模式的优势,并进行了突破:强调参与学校变革行动的中小学的数量为两所及以上,且学校教育质量是异质的,既有城市优质学校,也有城郊薄弱学校或乡村学校;U-G-S-S四方主体平等互动、各司其职。个案研究表明,U-G-S-S模式可以通过制度建构、任务驱动和文化营造促进各参与学校的整体发展,促进城乡义务教育均衡发展。U-G-S-S模式成功的三个主要要素:文化异质交融、知识多维共享、理论实践有机结合。
