摘要
受场地限制,某厂需在已有厂房内紧靠厂房柱基处建设永久性设备深基坑。经多种支护方案比较,最终采用带支撑的人工挖孔预应力悬臂桩支护及柱基托桩支承加固的结构方案。施工实践证实该方案可行。
Considering the limited construction field in a plant, a deep foundation pit need to be built for permanent equipments at stereobate close to existing plants. After comparison among different supporting schemes, strengthening scheme of manual hole digging prestressed cantilever piles borne on stereobate is adopt- ed finally. This scheme is proved to be feasible in construction practice.
