［摘要］華能山東石島灣核電廠高溫氣冷堆核電示范工程反應(yīng)堆廠房屋蓋系統(tǒng)采用單側(cè)鋼板混凝土空心組合結(jié)構(gòu)，屬于大跨度屋蓋體系，施工采用了模塊化技術(shù)。該技術(shù)包括各種模塊的制作及吊裝，設(shè)備吊裝口處屋蓋的施工，此外還要考慮電廠投入運(yùn)行后在役期間對(duì)屋蓋進(jìn)行臨時(shí)開(kāi)洞及重新封堵的要求。介紹的建造技術(shù)可滿足單側(cè)鋼板混凝土空心組合屋蓋設(shè)計(jì)時(shí)假定的結(jié)構(gòu)受力狀態(tài)，即施工期間屋蓋與側(cè)墻鉸接連接，只起到封閉廠房的作用；正常使用期間屋蓋與墻體固定端連接，參與廠房的整體結(jié)構(gòu)抗震作用。采用介紹的建造技術(shù)避免了設(shè)備安裝與屋蓋土建施工的交叉作業(yè)，降低了高空施工安全風(fēng)險(xiǎn)，可有效縮短總建設(shè)工期。

Abstract:The half-steel-concrete(HSC) hollow composite structure was used in the reactor building roof system of HuaNeng Shandong Shidaowan nuclear power plant HTR-PM demonstration project. This structure is a large-span roof system using modular construction technology. This technology consists of manufacture and hoisting of various modules, construction of roof at the presetting hole for hoisting, and the approach for temporary opening and re-enclosure of the roof during the service period after the power plant is put into operation. The construction method can satisfy the assumed stress state of the design of the HSC hollow composite roof. The roof is hinged with the side wall only for closing the plant during the construction. During the normal service period, the roof is fixed with the side wall and participates in the seismic resistance of the overall structure of the plant. In addition, the construction technology is adopted to avoid the cross operation of the equipment installation and the roof construction, which reduces the risk of the high-altitude construction, and can effectively shorten the total construction period.

Keywords:nuclear power plant; modularization; construction of concrete without framework
