【摘要】：鋼板樁圍堰水下施工具有危險(xiǎn)性。為了確保鋼板樁圍堰施工安全,以天津海河特大橋R#38墩基礎(chǔ)的鋼板樁圍堰為工程實(shí)例,采用有限元軟件ANSYS建立鋼板樁圍堰空間有限元模型,考慮了4種工況,進(jìn)行了有限元施工分析。計(jì)算結(jié)果表明:R#38墩基礎(chǔ)的鋼板樁圍堰的強(qiáng)度和變形滿足要求,可以按設(shè)計(jì)安全施工。本文可為同類鋼板樁圍堰的安全施工分析提供參考。
[Abstract]:The underwater construction of steel sheet pile cofferdam is dangerous. In order to ensure the safety of steel sheet pile cofferdam construction, taking the steel sheet pile cofferdam of Tianjin Haihe Bridge as an engineering example, the spatial finite element model of steel sheet pile cofferdam is established by using finite element software ANSYS, and four kinds of working conditions are considered. The finite element construction analysis is carried out. The calculation results show that the strength and deformation of the steel sheet pile cofferdam of R 鈮，
