Firstly,by the analysis of influencing factors of settlement of loessal foundation, results indicated that among the three settlement methods such as the layer-wise summation method based on chord modulus, the layer-wise summation method based on modulus of compressibility and the layer-wise summation method based on modulus of deformation and so on, the layer-wise summation method based on chord modulus is superior to the other two methods and is very close to the actual measurement settlement of building according to the grey incidence analysis on influencing factors of settlement.

本文采用灰色系统理论中的关联分析法对黄土地基变形进行了因素关联分析，并取得一些成果。通过分析影响黄土压缩变形的因素，对于沉降变形因素的关联分析，在对影响变形的诸因素进行分析的基础上，最终证明选择了四种因素作为确定弦线模量表依据的正确性，证明了据此建立的以弦线模量为基础的变形定量分析的表达式是可行的。从关联分析以及弦线模量法的简便、直观、便于推广应用的特点来看，弦线模量法计算沉降是值得大力推广的。

Secondly, by the analysis of influencing factors of collapsibility of loessal foundation, results indicated that at the basis of the grey incidence analysis on influencing factors of collapsibility of loessal foundation,the void ratio is the superior and steadily influencing factor of collapsibility at all events and other influencing factors will have different degree of influence according to the specific conditions of loess foundation.

通过分析影响黄土湿陷性变形的因素，对于湿陷变形因素的关联分析，可以看出土性指标对湿陷性的影响程度，孔隙比的影响比较突出，基本上可以认为是在土性指标对湿陷性的影响程度中最大的，其它指标会因土质含量、黄土的类型不同而影响各异。总之，本文应用灰色系统理论的关联分析法对应用广泛的工程实用模型变形计算方法做一些因素分析、进行反思，同时证明了弦线模量法计算沉降是值得大力推广的，弦线模量法计算沉降在将来的工程实践中必将带来更为可观的社会经济效益。
