毕业设计题目省老年人活动中心基坑工程设计与施工组织学院土木建筑学院专业土木工程专业班级土木1001班学生马福栋学号20100221160指导教师刘燕二〇一四年五月二十三日I济南大学毕业设计摘要随着社会的发展,人口的增多和城市化的快速发展,人们对住房的要求越来越迫切,城市中的建筑物越来越集中,我国是世界上人口最多的国家,要以有限的耕地面积养活13亿的中国人,就必须将人口集中起来,让出更多的耕地,因此,建筑形式向着更大、更高、更深、更集中的方向迈进,这就对基坑的开挖提出了更高的要求。并且现阶段基坑的设计理论不够成熟,更多的是以经验形式进行设计,再加上地形、土质、地下水等不确定因素,导致基坑事故频发。本文从基坑的设计和施工两个方面讨论了关于省老年人活动中心的基坑开挖的有关问题。该基坑设计采用了土钉墙的支护方案,降水采用了集水明排的方法降水,对基坑开挖过程中进行实时的监测,对施工进行合理的安排,使之安全、有序和高效的进行。关键词:基坑;土方开挖;土钉墙;III济南大学毕业设计ABSTRACTWiththedevelopmentofthissociety,thepopulationisincreasingandtheurbanizationisinrapiddevelopment.Alltheseleadstopeople’surgentrequirementforhousingandthenbuildingsincitiesbecomemoreandmorecentralization.Ourcountry’spopulationismaximumupto1.3billionintheworld.Itisessentialforustocentralizehumansandemptyoutmorearablelandsothatallpeoplewon’tbehungry.Fromthissense,architecturalformsneedstostridetowardbeingmorelarger,higher,deeperandcentralized,whichmakesahighclaimtopitexcavation.However,sincethedesigntheoryofexcavationisimmature,peoplealwaysdesignitdependingontheirownexperience.Besidesthis,theuncertainfactorsofterrain,soiltexture,groundwaterallleadtotheaccidentsofexcavationhappeningfrequently.Thispaperdiscussestheitemrelatingtothepitexcavationoftheprovincialelderlyactivitycenter,whichinvolvestwoaspectsofdesigningandconstruction.Thefoundationpitdesignusesthesupportingschemeofsoilnailedwall.Andthemethodofopenpumpingisappliedinprecipitation.Duringtheprogressofpitexcavation,instantmonitoringiscarriedoutandrationalconstructionschemeispracticable.Itwillbeconductedsafely,orderlyandeffectively.Keywords:pit;excavation;Soilnailingwall;IIIII济南大学毕业设计目录摘要………………………………………………..…….….…………….………………IABSTRACT…………….……………………..…………….……………………………II1前言……………………….…………………………………………….….…………….12工程概况......................……..….………………………….…..….…………………….23设计依据......................……..….………………………….…..….…………………….33.1图纸及地质报告…………………………………………………………………..33.2现行国家、行业、地方规范标准…………………………….………………...…34基坑支护方案选择......................……..….………………………….…..….………….44.1周边环境…………………………………………………………………………..44.2地下水…………………………….………………...……………………………..44.3地质情况………………………………………………………………............…..44.3.1地层结构…………………………….………………………................…...44.3.2土层参数选取…………………………….……………………........……...54.4支护结构的比选…………………………….………………...…………....……..55支护方案的确定......................……..….………………………….…..….……....…..….75.1确定支护方案…………………………………………………………....………..75.2支护结构的具体方案…………………………….………………...……..………75...
