本科毕业设计（论文） 漯河市第二人民医院C区病房楼基坑支护设计与施工 专业名称： 土木工程专业 年级班级： 岩土09-3班 学生姓名： 指导教师： 河南理工大学土木工程学院 二〇一三年六月十日 摘 要 漯河市第二人民医院C区病房楼位于漯河市交通路201号场地呈长方形，地上建筑面积24183.962，地下室总建筑面积17422，是一幢16层大楼，框架剪力墙结构，地下1层基坑开挖深度为6m。本文先介绍了工程地质及周边环境情况，结合工程概况及其周边环境情况，参照现有基坑支护设计理论，本次设计采用了钻孔灌注桩加锚杆的基坑支护结构。 本次设计是根据国家现行建筑基坑支护技术规程，在给定地质勘察报告的条件下，进行基坑支护设计，主要目的是掌握基坑支护设计的方法。在土压力计算过程中，运用了朗肯土压力理论；在内力计算过程中，运用了等值梁法；在配筋计算过程中，参照了混凝土结构设计规范。计算过程中除了以国家现行建筑基坑工程技术规程为依据外还参考以往的工程实例，加强理论与实践的结合。本次设计的主要指导原则是如何保证基坑的安全可靠、方便施工，并达到经济的效果。通过本篇论文，直观的说明了钻孔灌注桩加锚杆支护设计所需的参数。 [关键词]：基坑支护；朗肯土压力理论；等值梁法；钻孔灌注桩锚杆。 Abstract The Luohe second Peoples Hospital C area hospital ward building is located in Luohe transportation road 201st. The site is a rectangle, length 72m, width 31m, the area of ground floor is 24183.96 square meters, the basement total floor is 1742 square meters in area, it is a 16-storey building, frame - shear wall structure, the actual structure excavation depth of the basement is 6m. This article first introduces engineering geology and the surrounding environment, combined with the project general situation and its surrounding environment situation, refers to the existing pit-retaining structure design theory, this design uses the bored pile to add the pit-retaining structure of anchor rod. This design is according to national present construction pit-retaining structure technical schedule, under assigning condition of geological prospecting report, carries on the pit-retaining structure designs, the main purpose is to master the design method of pit-retaining structure. In the process of earth pressure calculation using the Rankine earth pressure theory; In the process of internal force calculation with the use of the equivalent beam method; In the process of reinforcement calculation, with reference to the concrete structure design code. The calculation process not only take the current national building foundation pit engineering as the basis, but also refer to the previous projects, strengthen the combination of
