In the renovation of Huangpi Wuhu pumping station in Wuhan, there were abutments for water pipes under the single-storey masonry vacuum braker room, which intersected the room obliquely. In order to avoid disturbance, foundation could not be built on the abutments. Meanwhile, the spacing of abutments is small, and the bearing capacity of foundation soil is very weak. To solve these prtblems, foundation beams were set under the masonry structure to cross the abutments, oblique independent foundations were built between the abutments, and load was transferred to the foundations though columns. By arranging the components reasonably, they can go well with obstacle. A novel foundation design is proposed to ensure the construction of this project, which meets design requirements in limited space.%武汉市黄陂武湖泵站改造工程中,单层砌体结构的真空破坏室下分布有泵站的出水管道及墩台,并与真空室斜向相交.为避免扰动,不能将基础置于墩台上;且由于墩台间距较小,地基承载力偏弱.为此在砌体结构下设置基础梁跨越墩台,在墩台间修筑斜向的独立基础,通过柱将梁上的荷载传递到基础上.经合理布置基础构件,使其与地下障碍物互不干扰,在有限空间内满足了设计要求,保证了顺利施工.
