新华社长春８月２日电（齐中熙、刘凤翥）吉林省第一条地铁——长春地铁１号线控制性工程，解放大路车站８月２日全面开工，这是我国东北高寒地区正在建设的最大规模的地铁暗挖换乘车站。

    The xinhua news agency on August 2, changchun（JiZhongXi、LiuFeng Zhu）Article 1 the jilin province--changchun metro line 1 bottleneck project，Liberation road station on August 2, fully operative，This is our country's northeast cold area is the largest of the construction of the underground subway transfer station。

    解放大路地铁车站位于长春市中心的人民大街与解放大路十字路口交会处，是长春地铁１号线与即将开工建设的地铁２号线的换乘车站。深入地下３１米的车站分为上下两层，总建筑面积约３２９００平方米，全部采用地下暗挖施工新技术，是我国东北高寒地区正在建设的规模最大、地质条件和施工工艺最复杂的地铁暗挖换乘车站。

    Liberation road subway station is located in the center of the changchun city people's street and liberation road crossing deeply，Is changchun metro line 1 and will start to be construction of the metro transfer station。31 meters deep underground station is divided into the upper and lower levels，With a total construction area of about 32900 square meters，All the underground concealed excavation construction new technology，Is China's northeast cold area is the largest construction、The geological condition and the construction technology of the most complex underground subway transfer station。

    承担施工任务的中国铁建十八局集团三公司项目经理胡恒千介绍说，整座车站就是建在一个地质破碎带上，它要穿越地震断裂带和含水量非常丰富的软土地层，地下管线和人防工程又非常集中，施工技术难度和工程风险都相当高。

    Undertake the task of construction China railway construction ShiBaJu group three project managers HuHengQian introduced said，Entire station is built in a geological broken belt，It across the seismic fault line and the water content of the very rich soft soil layer，Underground pipeline and civil air defence works and very concentrated，Construction technical difficulties and project risk are quite high。

    胡恒千说，采用地下暗挖技术的目的，就是要最大限度地减少建设过程中，对城市中心区地面交通和周边建筑的干扰和影响，但是它对施工技术和工艺提出了更高的标准，设计要求施工过程中地面和地下建筑物的沉降量最大不能超过３公分，目前国内地下工程建设所有的新技术、新工法都将在这座车站中得到应用。

    HuHengQian said，The purpose of the underground underground excavation，Is to minimize the construction process，City center on the ground transportation, and the buildings around the interference and influence，But its construction technology and process to put forward the higher standards，The design requirements during the construction of the ground and underground building settlement of the largest no more than 3 cm，At present domestic underground engineering construction all the new technology、The new method will be used in the station in。

    十八局集团三公司长春地铁项目党委书记王奎军告诉记者，工程建设中还将展开“复杂环境下深基坑降水设计与施工”、“群洞效应地表沉降控制技术”等一系列地铁暗挖综合施工技术的科研课题研究，为我国超大型、现代化地铁枢纽车站的建设积累经验。

    ShiBaJu group three company changchun metro project secretary of the party committee WangKuiJun told reporters，Project construction will begin“Complex environment design and construction of the deep foundation pit precipitation”、“Group of hole surface subsidence control technology effect”And a series of the subway underground construction technology of scientific research of comprehensive research，For our country's super、The construction of the modern subway hub station by experience。

    作为长春市轨道交通的骨干线路，地铁１号线全长约３７公里，分两期建设。一期工程设１６座地下车站。２０１５年建成通车后，日客流量可达１００万人次。

    As the backbone of changchun city rail transit line，Metro line 1 about 37 km length，Points two phase of construction。A set of 16 a underground station project。Built in 2015 after the opening to traffic，Passenger can, to 1 million people。
