基坑土钉墙设计毕业设计方案.doc

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土钉墙支护及其施工、监测。第二篇为专项设计，即桩基本设计。
第一篇共有七章，第四章、第五章、第六章为重要内容。通过对所给工程概况分析，结合支护方案选取根据、原则和办法，拟定了土钉支护方案。一方面对土钉详细参数进行拟定，涉及稳定性分析，计算土压力，拟定土钉布置，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，土钉详细参数拟定是重点。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，因而，作者对施工和监测方案作了详细规定。
第二篇是专项设计，通过对桩基本理解和学习，并结合建筑规范，完毕了最后设计。

Abstract
This has two prioritis，the first priority design，namely northern and southern sides of 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 made specific provision for the construction and monitoring program.
Article 2 is the project design,Via the studying the knowledge of the pile foundation，and the building codes，the author has completed the final design.
Keywords pit soil nail stability the pile foundation
