以武汉西四环通顺河大桥为依托，研究超宽变截面0#块支架及临时固结一体化施工技术。针对通顺河大桥超宽、变截面以及大跨度等特点，研究并采用了超宽变截面0#块支架及临时固结一体化施工技术和金钢绳锯切除刚结构混凝土临时固结块技术。这两项技术的成功应用，不仅最大限度地节省了费用、缩短了工期，在以后同类桥梁0#块设计与施工过程中也具有借鉴意义。
以武漢西四環通順河大橋為依託，研究超寬變截麵0#塊支架及臨時固結一體化施工技術。針對通順河大橋超寬、變截麵以及大跨度等特點，研究併採用瞭超寬變截麵0#塊支架及臨時固結一體化施工技術和金鋼繩鋸切除剛結構混凝土臨時固結塊技術。這兩項技術的成功應用，不僅最大限度地節省瞭費用、縮短瞭工期，在以後同類橋樑0#塊設計與施工過程中也具有藉鑒意義。
