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 2 Abstract This has two prioritis, the first priority design, namely northern and southern side sof the Huahai building foundation education soil nailing wall and its construction and monitoring. Article 2 for the project design, and the design of pile foundation. First there were seven chapters, the fourth chapter, the fifth chapter, the sixth chapter as the main content. Through the analysis of the project profile , the supporting scheme selection principle, basis and method, the soil nailing support scheme. First to determine the specific parameters of soil nailing, including the stability analysis and calculation, the soil nailed soil pressure to decorate, then the stability checking: local stability and overall stability checking. Among them, soil nail specific parameters is the key. Construction scheme and the soil nailing later in order to guarantee the safety in the process of the construction of soil nail and monitoring , therefore, the author has m ade specific provision for the construction and monitoring program. Article 2 is the p roject design, Via the studying the knowledge of the pile foundation, and the building codes, the author pleted the final design. Keywords pit soil nail stability the pile foundation 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.......................................... 1 设计目的和意义....................................................................................................... 1 基坑工程的内容....................................................................................................... 3 深基坑支护中的几个热点问题............................................................................... 5 深基坑工程
