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AbstractThishastwoprioritis,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目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc263969494"第一篇黄岛华海大厦基坑土钉墙设计PAGEREF_Toc263969494\h1HYPERLINK\l"_Toc263969495"第一章绪论PAGEREF_Toc263969495\h1HYPERLINK\l"_Toc263969496"设计目的和意义PAGEREF_Toc263969496\h1HYPERLINK\l"_Toc263969497"基坑工程的内容PAGEREF_Toc263969497\h3HYPERLINK\l"_Toc263969498"深基坑支护中的几个热点问题PAGEREF_Toc263969498\h5HYPERLINK\l"_Toc263969499"深基坑工程特点PAGEREF_Toc263969499\h8HYPERLINK\l"_Toc263969500"第二章工程概况PAGEREF_Toc263969500\h10HYPERLINK\l"_Toc263969501"场地岩土工程条件PAGEREF_Toc263969501\h10HYPERLINK\l"_Toc263969502"2.2场地水文地质条件PAGEREF_Toc263969502\h11HYPERLINK\l"_Toc263969503"
