摘要
本设计为泛海酒店基坑支护结构设计，该基坑位于黑龙江省佳木斯市境内，基坑长为55m,宽为45m。厂区内地形整体呈现则矩形，基坑开挖深度为9m,北侧为居民楼，基础埋深为2m,距基坑最近距离为2.5m，其余三侧建筑物距基坑较远。通过方案比选，最终确定北侧采用混凝土桩锚杆支护结构设计，南侧为幸福路，采用土钉墙锚杆支护结构设计，东西两侧采用钢板桩锚杆支护结构设计。
本次设计主要内容包括：设计方案必选；土压力计算；支护结构计算；基坑稳定性验算；支护结构的配筋；基坑的降水止水设计；基坑监测方案设计。
经验算，该基坑设计合理，方案可行，满足泛海酒店基坑的服务水平。

ABSTRACT
The design for the Asia Standard Hotel Excavations design, the foundation pit in Jiamusi City, Heilongjiang Province, territory, pit length 55m, width 45m. Plant in the region as a whole showed the rectangular terrain, excavation depth of 9m, north of the residential building, foundation depth of 2m, distance from the nearest pit 2.5m, the remaining three sides of the building farther away from the pit. Through Alternatives. Finalize the north side of the concrete piles using bolting structural design, south of Xingfu Road, using soil nail wall bolting structural design, east and west sides by steel piles bolting structural design.
The design of the main contents include: Design Required; earth pressure calculation; supporting structural calculations; foundation stability checking; supporting structure reinforcement; precipitation sealing pit design; excavation monitoring program design.
Experience count, the pit design is reasonable, feasible, to meet the level of service of Fan hai Hotel pit.
Key words, the foundation design is reasonable, feasible, meet the hotel foundation service level.
