本科毕业论文人工冻结发的施工技术研究摘要：本文首先介绍了选题的目的与意义、国际及国内人工冻结法的研究与应用现状及冻胀融沉机理及试验研究。接下来介绍了人工冻土的分类和构造以，及地下水对冻土形成的影响。在冻土形成的过程中，物理力学性质也发生了很大的变化，于是在文中进一步研究了冻土的抗拉强度、抗压强度、抗剪强度。并阐述了人工冻结法的原理、设计以及冻结壁形成过程中温度场的变化。在上述理论的基础上，进一步了解冻结法的设计和施工。于是本文主要从冻结方案选取、冻结孔的布置与施工以及土体开挖过程对人工冻结法进行阐述。最后结合某地铁隧道联络通道冻结法施工技术，对人工冻结发法在实际工程中的应用，进行了深一步的了解。关键词：人工冻结法、冻土、冻结壁、冻结孔Abstract:Frist,thispaperintroducesthetopicsofthepurposeandsignificanceofinternationalanddomesticArtificialFreezingMethodResearchandApplicationStatusandfrostthawMechanismandExperimentalStudy.Nextcomestheclassificationofartificialfrozensoilandstructure,aswellastheimpactofgroundwaterontheformationofthefreezingsoil.Intheprocessoftheformationofthefreezingsoil,thephysicalandmechanicalpropertiesgreatchangeshavetakenplace.Sothispaperstudythetensilestrength,compressivestrengthandshearstrengthofthefreezingsoilinthetextforfurther.Anddescribestheprinciplesofartificialfreezingmethod,design,andthechangesofthefreezingwalltemperaturefieldduringtheformation.It’sbasedontheabovetheory,learnmoreaboutthedesignandconstructionoffreezing.Thenselectofthearticleelaboratesartificialfreezingmethodfromthefrozensolution,freezingholelayoutandconstructionaswellasduringtheexcavationofsoil.Finally,asubwaytunnelconnectingpassagefreezingconstructiontechnology,madeofartificialfreezingmethodinpracticalengineeringapplications,conductsadeepunderstandingofstep.Keywords:artificialfreezing,frozen,freezewall,freezingholePAGE\*MERGEFORMAT63目录TOC\o"1-3"\h\uHYPERLINK\l_Toc4605第一章绪论PAGEREF_Toc46055HYPERLINK\l_Toc43191.1选题意义PAGEREF_Toc43195HYPERLINK\l_Toc278811.2问题提出PAGEREF_Toc278816HYPERLINK\l_Toc258361.3国内外研究现状PAGEREF_Toc258368HYPERLINK\l_Toc220021.4冻胀融沉机理及试验研究PAGEREF_Toc2200210HYPERLINK\l_Toc16229第二章冻土描述及其性质PAGEREF_Toc1622911HYPERLINK\l_Toc139302.1冻土定义PAGEREF_Toc1393011HYPERLINK\l_Toc154672.2冻土分类PAGEREF_Toc1546711HYPERLINK\l_Toc65652.2.1按含冰特征PAGEREF_Toc656511HYPERLINK\l_Toc253332.2.2
