Undertaking the construction in loess areas is necessary to take certain measures to deal with the foundation of the building in order to improve the physical and mechanical properties of the soil and also to reduce or eliminate the collapsibility of loess foundation to ensure the safety of the building. Currently, the research of collapsible loess foundation treatment is generally obtained by mechanical calculations or through the experiment. It is not likely to select the treatment based on each factors. For a specific project, there may be several kinds of treatment for collapsible loess foundation treatment. However, the selection of the treatment is usually affected by the subjective experience of the designer .And it is always hard to achieve optimal .Therefore, a method of collapsible loess foundation treatment is created through the factors of those means based on the previous research. Specific steps: (1) The advantages and disadvantages, scope, uncertainty of the method of each collapsible loess foundation treatment method are analyzed in details. (2) For a specific engineering project, the treatment of collapsible loess foundation is optimized and the feasibility is verified through AHP model ,evaluation index system and the combination of the AHP and value engineering. Key words collapsible loes foundation treatment program optimization 目录 第1章 绪论 1 1.1 研究背景 1 1.2 湿陷性黄土地基的概述 1 1.2.2 湿陷性黄土场地的湿陷等级 2 1.3 湿陷性黄土的物质构成 2 1.3.1 物质成分 3 1.3.2 组织结构 3 1.4 湿陷性黄土地的物理、化学性质及工程特性 3 1.5 研究目的及其意义 4 第2章 湿陷性黄土地基处理措施
