摘　　要：鄂北地区水资源配置工程战线长,且多地段存在膨胀土,因此对大重量现浇混凝土渡槽支撑系统施工方案的选择及细致分析非常重要。以该工程2016年第2标段为例,对大重量现浇渡槽碗扣式满堂支架和钢管柱贝雷梁组合支架的方案选择、地基处理和预拱值确定等几个重点问题进行了探讨,指出了需要重点注意的一些问题。同时,对在膨胀土地区使用碗扣式满堂支架和钢管柱贝雷梁组合支架提出了一些新的观点。Due to long construction period of Water Allocation Project and existence of explosive soil in many parts of North Hubei Province, it is crucial of having careful selection and detained analysis for the supporting system of big weight cast-in-situ aqueduct. Taking No.2 bidding section of 2016 as an example, discussions are made on comparative selection between cuplok full support system and bailey beam combination stent, foundation treatment, as well as defining of pre-cambering value. Problems that need special focus on and new ideas are proposed for the adoption of cuplok full support system and bailey beam combination stent in expansive soilarea.
