摘 要
随着公路建设的快速发展，全国各地结合软土路基工程的设计与施工越来越广泛，通过大量的试验研究与理论分析，已取得较丰富的实践经验。
软土地基处理的方式多种多样，各有各的优缺点及其局限性，公路对路基沉降的要求很高，路基失稳或过量沉降等现象经常发生，如何选择正确的地基处理方式直接关系到工程质量、投资和进度。
本文主要介绍了地质条件较特殊地段软土地基处理常用的两种方法，即碎石桩和粉喷桩法。本文对这两种方法的基本理论、具体的设计和施工技术要点进行了详细的比较分析，并从适用范围、处理效果和施工角度等方面比较其优缺点、适用性。通过本文得出不同的软土地基可采用不同的处理方法，依据各种软土地基处理方法的原理，并根据土质类型、地基条件、道路条件、施工条件和建设费用合理选择恰当方法，来获得最佳的处理效果。

Abstract
With highway construction and rapid development in all parts of the country with soft soil subgrade the design and construction of more and more extensive, through a lot of experiments and theoretical analysis has been made more abundant practical experience.
Soft Ground 毕业论文http://www.751com.cn/ 论文网http://www.lwfree.com/settlement frequent phenomenon, how to choose the correct foundation approach is directly related to the quality of the project, investment and progress.
This paper introduced the special geological conditions than soft ground handling lots of two commonly used methods, and that the gravel pile DJM law. In this paper, these two methods are the basic theory, the specific design and construction techniques for the detailed comparative analysis from the scope of treatment effect and construction perspective aspects of its advantages and disadvantages, applicability. Through this paper, a different soft ground using different ways of handling it, Soft Ground based on various methods of treatment principles, and in accordance with the soil type, ground conditions, road conditions, Construction costs for building and the appropriate way to a reasonable choice to receive the best treatment effect.
