吉林市经济技术开发区场地稳定性分区与评价

The Division and Evaluation of the Site Stability in the Economy and Technology Developing Area of Jilin

在对吉林经济技术开发区工程地质概括地描述、分析的基础上，选取地面坡度、切割深度、冲沟长度、卵砾石埋深、地下水埋深、平均剪切波速、负５ｍ切面岩性和断层性质为评价因子，利用模糊综合评判的方法，对场地稳定性进行分区和评价，并在权重的选取上提出一种新的思路。

In this paper, on the basis of illustrating and analyzing the general situation of engineering geology in Jilin economy and technology developing area, the earth's surface gradient, the erosion length, the depth of erosion, the gravel burried depth, the depth of underground water, the average velocity of shear elastic wave, the character of rock 5 meter under ground and the fault character are selected as the evaluation elements to divide and evaluate the site stability area through the method of fuzzy comprehensive evaluation. A new way of thought on how to select the weights is also presented.
