辦好2022年北京(jing)冬奧(ao)會是實施京(jing)津(jin)冀協同發展戰(zhan)略的重要舉措。為加(jia)快建(jian)(jian)(jian)設體(ti)育強國(guo)(guo)，推動(dong)新(xin)時代體(ti)育事業高(gao)質(zhi)量發展提(ti)供了歷史性機遇，對于展現(xian)國(guo)(guo)家形象、促(cu)進國(guo)(guo)家發展振奮民(min)族精神具有重大(da)意(yi)義。中(zhong)建(jian)(jian)(jian)三局承建(jian)(jian)(jian)多項(xiang)冬奧(ao)會場館(guan)(guan)及配套工程。近日(ri)，國(guo)(guo)內首(shou)個以冬奧(ao)會為主題全國(guo)(guo)規模(mo)最(zui)大(da)、展品最(zui)豐(feng)富的冰雪主題博(bo)物(wu)館(guan)(guan)——崇禮冰雪博(bo)物(wu)館(guan)(guan)項(xiang)，提(ti)前12天(tian)完成主體(ti)結構封(feng)頂。
崇禮冰(bing)雪(xue)(xue)博(bo)物(wu)(wu)館采用博(bo)物(wu)(wu)館、圖書(shu)館“兩館合一”的建(jian)筑方式。主要(yao)由序廳(ting)、冰(bing)雪(xue)(xue)運動歷(li)史廳(ting)‘、冬奧歷(li)史廳(ting)、北京(jing)冬奧廳(ting)4個(ge)功能廳(ting)和1個(ge)冰(bing)雪(xue)(xue)運動體驗區(qu)組(zu)成(cheng)(cheng)。工程建(jian)成(cheng)(cheng)后將成(cheng)(cheng)為推廣傳播世界(jie)冰(bing)雪(xue)(xue)運動，研究冰(bing)雪(xue)(xue)文化的重要(yao)基(ji)地(di)。
