摘　　要：某小区设计为超大型半地下室,由于多方面原因,塔式起重机拆除困难。通过结构验算,明确了梁板加固方案,即用覫48×3.5钢管作为临时顶撑(间距0.6m×0.9m),上下用槽钢垫平后再用木塞塞紧,或用螺旋式可调托撑顶紧,保证了起重机行走和拆卸作业时主体结构的绝对安全;分析同类型结构施工时水平和垂直运输,为超大型半地下室的设计与施工提供了参考意见。A community dismantle the tower crane. adopts super-large semibasement. But due to various reasons, it is difficult to Through structural verification, beam slab strengthening method is determined, namely ￠48×3.5 steel pipes are used as temporary top brace （with spacing 0.6m×0.9m）, channel steels are packed on the top and under the bottom, and then wooden wedge is inserted tightly and the beam slab issupported hghtly by screw-type adjustable support, to guarantee that the main structure is absolutely safe during travel and dismantlement of crane; experiences are concluded, it is analyzed how to solve horizontal and vertical transportation problems during construction of similar structures, providing some references for the design and construction of super-large semibasement.
