The first part of the paper is introduction. It expatiates on the current situation of foundation pit，methods in common use and its develop trend .It essentially relate the problems in the retaining structures design of deep foundation pit at present, and the direction for engineer to make efforts, so as to go a step further discussion. The second part of the paper is the design for the deep foundation pit of the CBD international edifice. It is composed of ground dewatering design, retaining structure design and master project planning and scheduling document. Brief introduction of the project, conceptual design, quantity list, design results collecting and construction planning and scheduling document are included. The main points of it are conceptual design and computation. Dug well are adopted according to the depth of foundation pit and site condition, and design of it is performed. It is analyzed that how to choose reasonable types of retaining structures according to different environment conditions. The chosen retaining structures are subjected to counter force computation，bending moment computatation, length design of anchor rods, tendon design of anchor rods, section design of cast-in situ pile, overall stability checking calculation of anchor rod, checking calculation on safety against overturning，anti-hunch safety checking calculation, diameter and length of soil nail computations, anti-slide and anti-overturn calculations of soil nail. At last, construction planning and scheduling document which includes site layout, ground dewatering design，soil excavation, construction of retaining structures and the schedule of the project is given.The third part of the paper - English translation, the theme is gravity-type retaining walls on support structures. Outlines the types of retaining walls, mainly on the size of the gravity of parapet, the edge of a gravity-type suffered stability analysis and the final sample to a specific gravity of the retaining wall design.Keywords: Deep Foundation Pit; Soil pressure; Distribution; Conceptual Design; Retaining wall目 录1 绪论1 1.1前言1 1.2基坑工程设计研究的进展情况12 工程简介6 2.1工程关系6 2.2工程概况6 2.3地形、地质条件7 2.3.1工程地质条件7 2.3.2水文地质条件73 方案设计10 3.1降水方案设计10 3.1.1水文地质条件10 3.1.2周边环境条件10 3.1.3降水工程分析及方案选择10 3.2边坡支护方案设计11 3.2.1边坡支护的目的11 3.2.2支护工程分析114 方案设计计算书13 4.1降水计算13 4.1.1确定井点管埋深H13 4.1.2计算基坑涌水量Q13 4.1.3确定单井出水量q14 4.1.4计算井点管数量n14 4.1.5求井点管间距D14 4.1.6降水深度复核14 4.1.7选择抽水设备15 4.2支护计算15 4.2.1水平反力计算15 4.2.2弯矩计算22 4.2.3锚杆长度计算34 4.2.4锚杆锚索计算39 4.2.5灌注桩截面设计40 4.2.6锚杆整体稳定性验算44 4.2.7抗倾覆安全验算51 4.2.8坑底抗隆起安全验算53 4.2.9桩墙底地基承载力验算55 4.2.10土钉墙支护设计565 设计结果汇总626 施工组织设计68 6.1施工部署68 6.1.1工程总体目标68 6.1.2项目管理机构设置68 6.1.3施工总体安排69 6.1.4基坑施工总体流程70 6.1.5劳动力安排计划70 6.1.6主要施工机械设备使用计划71 6.1.7主要材料使用计划73 6.2施工准备75 6.2.1现场准备75 6.2.2技术准备75 6.2.3物资准备76 6.2.4施工队伍准备76 6.2.5机械设备准备76 6.3施工测量77 6.3.1测量方法77 6.3.2测量人员78 6.3.3测量仪器78 6.3.4施工测量管理79 6.4降水施工79 6.4.1降水人员组织79 6.4.2主要材料、设备使用计划79 6.4.3施工工艺流程80 6.4.4控制措施81 6.4.5降水监测82 6.5土方施工83 6.5.1土方施工总体安排83 6.5.2土方开挖83 6.5.3马道设置及基坑收土84 6.5.4挖土注意事项84 6.5.5土方与其它工序的配合85 6.
