【摘要】：20世纪80年代,随着国内建设步伐的加快,为了适应工程建设的需求,桩锚支护结构开始在工程中初步得到应用,并逐步得到发展。因该支护形式具有成本低、施工易、技术要求低、环境影响小等优点,目前在深基坑的治理和滑坡的整治中得到了广泛的应用,也是目前深基坑支护工程中最常用的基本支护形式之一。对于桩锚支护结构的研究,也主要集中在计算理论、施工技术、应用领域等方面。本文从现有的基本计算理论出发,结合工程实例对深基坑桩锚支护结构的设计计算理论及方法进行了分析和研究:结合深基坑工程和桩锚支护结构的特点,对桩锚支护结构在深基坑工程中的应用和发展现状进行了归纳;通过对深基坑桩锚支护结构土压力计算理论进行归纳和分析,对各种计算理论的适用条件进行了总结;针对目前桩锚支护结构的计算理论和方法,比较和总结了各种计算理论和方法的适用条件及优缺点;对桩锚支护结构的设计方法进行研究,对支护结构及锚杆的稳定性进行了验算;结合工程实例,采用不同方法对深基坑桩锚支护结构进行了计算和分析,讨论不同计算方法的优缺点;总结深基坑桩锚支护结构的设计计算分析方法,为桩锚支护结构在深基坑中的设计计算提出建议。
[Abstract]:In 1980s, with the acceleration of the pace of domestic construction, in order to meet the needs of engineering construction, pile-anchor support structure began to be initially applied in the project. Because of the advantages of low cost, easy construction, low technical requirements and small environmental impact, this support form has been widely used in the treatment of deep foundation pit and landslide treatment. It is also one of the most commonly used basic supporting forms in deep foundation pit support engineering at present. The research of pile and anchor support structure is mainly focused on calculation theory and construction technology. This paper starts from the existing basic calculation theory. The design and calculation theory and method of pile-anchor support structure in deep foundation pit are analyzed and studied in combination with engineering examples: combined with the characteristics of deep foundation pit engineering and pile-anchor supporting structure. The application and development status of pile-anchor supporting structure in deep foundation pit engineering are summarized. Through the induction and analysis of the earth pressure calculation theory of the pile anchor support structure in deep foundation pit, the applicable conditions of various calculation theories are summarized. According to the calculation theory and method of pile and anchor support structure at present, the applicable conditions, advantages and disadvantages of various calculation theories and methods are compared and summarized. The design method of pile and anchor supporting structure is studied, and the stability of supporting structure and bolt is checked and calculated. Combined with engineering examples, different methods are used to calculate and analyze the pile-anchor support structure of deep foundation pit, and the advantages and disadvantages of different calculation methods are discussed. This paper summarizes the design calculation and analysis method of pile anchor support structure in deep foundation pit, and puts forward some suggestions for the design and calculation of pile anchor support structure in deep foundation pit.
