日前，上海建(jian)工(gong)(gong)(gong)(gong)機施集(ji)團軌交15號線姚(yao)虹(hong)路站(zhan)采(cai)用“預制+現澆迭合拱(gong)殼”工(gong)(gong)(gong)(gong)藝(yi)(yi)施工(gong)(gong)(gong)(gong)的無柱拱(gong)形頂板(ban)完成了極限工(gong)(gong)(gong)(gong)況加(jia)載試驗(yan)，各(ge)項監測數(shu)據全部達(da)到設計要求，該(gai)(gai)項試驗(yan)宣告成功。采(cai)用該(gai)(gai)工(gong)(gong)(gong)(gong)藝(yi)(yi)進(jin)行大(da)跨度拱(gong)殼結(jie)構施工(gong)(gong)(gong)(gong)，既符(fu)合裝配式建(jian)筑的發展導向(xiang)，提高(gao)工(gong)(gong)(gong)(gong)廠預制構件在結(jie)構中的比例，又可取消現場支模的繁重工(gong)(gong)(gong)(gong)作(zuo)，簡化(hua)現場施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序，提高(gao)施工(gong)(gong)(gong)(gong)效(xiao)率。同時，預制構件的制作(zuo)精度高(gao)，外觀質量好(hao)，易于(yu)實現清水混凝土的感(gan)觀效(xiao)果。在地鐵車站(zhan)中采(cai)用此工(gong)(gong)(gong)(gong)藝(yi)(yi)，由于(yu)沒(mei)有(you)中柱的遮擋，可使車站(zhan)內部空間更為開闊，大(da)幅增(zeng)加(jia)乘客的舒適感(gan)。
