基坑土钉墙设计(毕业设计)

山东科技大学毕业设计1摘要本文共有两篇，第一篇为主设计，即华海大厦基坑南北两侧的土钉墙支护及其施工、监测。第二篇为专题设计，即桩基础设计。第一篇共有七章，第四章、第五章、第六章为主要内容。通过对所给工程概况的分析，结合支护方案的选择依据、原则和方法，确定了土钉支护的方案。首先对土钉具体参数进行确定，包括稳定性分析，计算土压力，确定土钉布置，然后对其进行稳定性验算：局部稳定性和整体稳定性验算。其中，土钉具体参数确定是重点。土钉施工方案和其后期监测是为了保证施工及其运营过程中安全，因此，作者对施工和监测方案作了具体规定。第二篇是专题设计，通过对桩基础的了解和学习，并结合建筑规范，完成了最终的设计。关键字基坑土钉稳定性桩基础山东科技大学毕业设计2AbstractThishastwoprioritis,thefirstprioritydesign,namelynorthernandsouthernsidesoftheHuahaibuildingfoundationeducationsoilnailingwallanditsconstructionandmonitoring.Article2fortheprojectdesign,andthedesignofpilefoundation.Firstthereweresevenchapters,thefourthchapter,thefifthchapter,thesixthchapterasthemaincontent.Throughtheanalysisoftheprojectprofile,thesupportingschemeselectionprinciple,basisandmethod,thesoilnailingsupportscheme.Firsttodeterminethespecificparametersofsoilnailing,includingthestabilityanalysisandcalculation,thesoilnailedsoilpressuretodecorate,thenthestabilitychecking:localstabilityandoverallstabilitychecking.Amongthem,soilnailspecificparametersisthekey.Constructionschemeandthesoilnailinglaterinordertoguaranteethesafetyintheprocessoftheconstructionofsoilnailandmonitoring,therefore,theauthorhasmadespecificprovisionfortheconstructionandmonitoringprogram.Article2istheprojectdesign,Viathestudyingtheknowledgeofthepilefoundation,andthebuildingcodes,theauthorhascompletedthefinaldesign.Keywordspitsoilnailstabilitythepilefoundation山东科技大学毕业设计1目录第一篇黄岛华海大厦基坑土钉墙设计...1第一章绪论.......................................11.1设计目的和意义.....................................................................................................11.2基坑工程的内容.....................................................................................................31.3深基坑支护中的几个热点问题.............................................................................51.4深基坑工程特点.....................................................................................................8第二章工程概况.....................................102.1场地岩土工程条件...............................................................................................102.2场地水文地质条件..............................................................................................112.3场地周边环境条件...............................................................................................11第三章支护方案的选择.........................133.1基坑支护的类型...................................................................................................133.2基坑支护结构选择的依据、原则和方法...........................................................143.3土钉支护的工作性能............................................................................................18第四章支护体系具体支护参数确定.....204.1支护前稳定性验算...............................................................................................204.2土压力计算...........................................................................................................244.3土钉墙布置：.......................................................................................................294.4土钉长度计算及其局部验算：...........................................................................294.5整体稳定性验算如下...........................................................................................37第五章施工组织设计.............................405.1工程概况...............................................................................................................405.2施工前准备...........................................................................................................405.3施工部署与施工方案...........................................................................................415.4施工技术质量要求及注意事项...........................................................................43第六章基坑监测方案设计.....................466.1工程概况...............................................................................................................466.2监测意义...............................................................................................................466.3监测方案...............................................................................................................47山东科技大学毕业设计2第七章施工安全与对策.........................547.1停电预案措施.......................................................................................................547.2基坑支护结构安全预案措施...............................................................................547.3基坑周围管线安全应急预案措施.......................................................................54第二篇专题设计—桩基础设计.............56第一章概述.............................................561.1桩基础的使用.......................................................................................................561.2桩基础的类型.......................................................................................................571.3桩基础的设计原则...............................................................................................571.4桩基础的设计内容...............................................................................................57第二章工程概况.....................................59第三章桩基础设计.................................603.1选择桩形、截面...........
