DK23+721.346）,車站外包尺寸全長182.1m,主體建筑總面積7448m附屬建筑總

面積3584m2。盾構(gòu)井段基坑深約17.61m,基坑寬23.80m；車站主體標(biāo)準(zhǔn)段基坑深約

15.91m,基坑寬約19.7m。

車站采納明挖法施工，主體圍護(hù)結(jié)構(gòu)為800mm地下連續(xù)墻+內(nèi)支撐（第一道支撐

采納混凝土支撐，支撐斷面為700x900mm；第二道支撐端頭井段采納鋼筋混凝土支

撐，支撐截面均為700x900mm；標(biāo)準(zhǔn)段采納0800,t=16mm的鋼支撐；第三道支撐采

納0609,t=16mm的鋼支撐）；本站共設(shè)置4個(gè)出入口、2組風(fēng)亭、1個(gè)消防疏散口，

圍護(hù)結(jié)構(gòu)為SMW工法樁+內(nèi)支撐。基坑平安等級為一級。

該站分兩期施工：第一期交通疏解將震澤路交通向北側(cè)翻交，供機(jī)動車雙向4車

道及人非2車道通行，本期笫一階段分為兩個(gè)作業(yè)面施工車站主體結(jié)構(gòu)局部，笫二階

段施工南側(cè)附屬結(jié)構(gòu)及內(nèi)部二次結(jié)構(gòu)；第二期交通疏解將交通復(fù)原至車站主體結(jié)構(gòu)上

方，震澤路交通復(fù)原為雙向6左道（機(jī)動車道）+雙向2個(gè)人非車道，分為兩個(gè)作業(yè)

面同時(shí)施工北側(cè)出入口等附屬工程及車站剩余內(nèi)部二次結(jié)構(gòu)等。

商務(wù)中心站東西端頭受污水主管影響，需在污水管遷改后進(jìn)行清障處理，清障采

納拉森鋼板樁+3道鋼支撐的支護(hù)形式。

小里程端均為盾構(gòu)始發(fā)，大里程端均為盾構(gòu)二次始發(fā)。
