摘要
本文依托华容煤炭铁水联运储配基地码头一期工程的岸坡双排钢板桩支护工程,采用有限差分程序FLAC3D对岸坡开挖后的支护结构、边坡及临岸防洪大堤进行了三维建模和计算。结果表明,在双排钢板桩支护下岸坡基本稳定,防洪大堤变形满足规范要求;钢板桩及边坡变形在三维空间上具有差异性,开挖区中部变形最大,向两侧逐渐递减,未开挖段钢板桩对开挖段钢板桩的位移有一定的约束作用。
This paper is based on the double-row steel sheet pile support project of the bank slope in the first-phase project of the wharf of the Huarong Coal Iron-water Combined Transport Storage and Distribution Base.The finite-difference program FLAC3D is used to conduct three-dimensional modeling and calculation of the support structure,slope,and the flood-control dyke near the shore after the bank slope excavation.The results show that the bank slope is basically stable under the support of the double-row steel sheet piles,and the deformation of the flood-control dyke meets the specification requirements.The deformation of the steel sheet piles and the slope shows differences in the three-dimensional space.The deformation in the middle of the excavation area is the largest,gradually decreasing towards both sides.The steel sheet piles in the non-excavation section have a certain restraining effect on the displacement of the steel sheet piles in the excavation section.
