1、本科生毕业设计(论文)题目:温泉公寓2号楼基坑支护设计（地下水位-1.5m）英文题目:Hotspringapartment2ndbuildingholeexcavatedforbuildingfoundationsupportsandprotectionsdesign（Theundergroundwaterlevel-1.5meters）系:土木工程系专业:土木工程班级:学生:学号:11指导教师:职称:指导教师:职称:-3-摘 要拟建中的温泉公寓2号楼位于苏州新区，西邻珠江路，北邻竹园路，场地以北为已建一期工程。由苏州高新技术创业中心投资建设，由4幢高层及裙房，附带
2、下沉式广场及餐饮娱乐设施组成，场地下均设有两层地下室相连通，为框剪和框架结构。建筑场地地表绝对标高在+2.48m和+3.85m之间，以1985国家高程基准为准。基坑实际开挖深度分布：北侧约7.5m，西侧及南侧、东侧均为10m。基坑开挖深度在7.00m-9.00m之间。全套图纸，加结合本工程地质、环境、挖深等诸多因素确定安全可靠的支护方案；为基坑土方开挖和地下室施工创造一个安全干燥的施工环境；考虑到邻近坑边有建筑和道路（下设有水、电、气等管线），为确保安全，以“变形”控制设计。本着“安全可靠、经济合理、技术可行、施工方便”原则，整个基坑采用一排钻孔灌注桩作挡土结构,锚杆
3、支撑(局部地段采用钢管竖向斜撑)作为支撑结构体系。基坑四周采用深层搅拌桩作止水帷幕。基坑内采用轻型井点降水+集水坑排水。-3-关键词：深基坑，支护结构，挡土结构，锚杆支撑-3-TheHotspringapartment2ndbuildingholeAbstractTheHotspringapartment2ndbuildingholeexcavatedforbuildingfoundationsupportsandprotectionsdesigninSuzhoucity,inthewesternofZhujiangRoadandnorthbehindZhuyuanR
