青岛地铁R3线地质条件评价研究

利用青岛地铁R3线井冈山路站—嘉年华站区间的地铁勘察资料,综合钻探、取样、物探、水文、地震、岩石试验等多方面的资料,提出了研究区工程地质评价因子,建立了青岛地铁地质条件评价的三级层次分析模型,通过评价因子量化分级和权重,对青岛地铁地质条件进行了综合评价。通过综合研究区地质条件评价结果,将研究区分为地质条件良好区、中等区、较差区和差区,同时对各区提出了工程风险控制措施。

The Geology Evaluation Research of Qingdao Subway

By using the exploration data of Qingdao subway R3 line from Jinggangshan to Jianianhua, and studying various data of drilling, sampling, geophysical prospecting, hydrology, earthquake, rock testing comprehensively, this essay gets the engineering parameters of the research area and makes a three-class hierarchies structural model to build a an evaluation system for geological conditions of Qingdao subway. By comparing the interaction of Qingdao subway and geological condition, this essay makes a quantitative classification system of various evaluation factors and figure up the weight of different factors with Analytic Hierarchy Process, meanwhile deal with the factors standardized by using composite-index assessment method, in order to get the evaluation result of Qingdao subway geological conditions. The evaluation result of the research area shows that it can be divided into four different areas: good geological condition area, moderate geological condition area, slightly poor geological condition area and poor geological condition area,and propose the risk control measures for each area
