预应力鱼腹梁易于施工且能够减少工期及工程造价,在深基坑支护中被广泛采用,通过某含厚层淤泥质土的基坑工程实例探讨了该支护结构的构造及支护特点,基坑壁深层水平向位移的监测显示,基坑壁最大水平向位移为15.6mm,符合工程设计要求,工程实例分析可为鱼腹梁的应用提供参考。
Prestressed fish-bellied girder has characteristics of easy construction, and which can reduce the construction period and project cost, it has been widely adopted by an engineering instance in deep excavation foundation.The support structure's construction and support features was analyzed through an excavation containing thick mucky soil in this paper, the deep horizontal displacement monitoring of pit wall show that the maximum horizontal displacement of pit wall is 15.6mm, in line with the requirements of engineering design, this engineering thesis case study can provide a reference for the application of the beam inside the fish.
