摘要
在工程勘察资料的基础上,采用定性与定量相结合的层次分析方法,筛选主要影响因子对咸阳市区建设用地质量等级进行评价,为城市规划及建设用地地价评估提供依据。研究结果表明:影响咸阳市区建设用地质量的主要因子除地基土承载力外,还需考虑黄土湿陷性和砂土液化等影响建筑地基处理成本的因素,地下墓穴坑洞与洪水淹没也是滨河古城建设用地质量评价中不可忽视的因素。咸阳市区土地质量可分五等,以二等地面积最大,一等地次之,三、四、五等地面积较小。
Based on the reconnaissance data of the building, the quality grade of the city land for constructing engineering in Xianyang downtown area was evaluated by choosing the main influence factor and adopting the AHP methods of qualitative and quantitative analysis, in order to provide the basis of the city planning and estimating the city land. The results show besides the foundation carrying capacity, the factors, such as loess wet-sinking and sandy soil liquefying are main factors that influence the cost of the constructing engineering in loess river valley region;the factors of underground grave pit and the flooding are needed to be considered at both riversides.The land quality in Xianyang downtown area is divided into five grades, the second grade land is the biggest one,followed by the first, third,fourth and fifth grade of land.
