Suitability evaluation method for engineering geology of excavation engineering in Beijing
-
摘要: 基于目前北京市中心城地下空间开发的趋势和地下空间开发中常用的基坑工程施工技术特点的基础上，采用层次分析法建立了一种适用于基坑工程地质条件适宜性评价的新方法。采用该方法计算所得结果可用于评价工程地质条件对基坑工程建设期和竣工后使用期的影响。该方法不仅可用以建立北京市地下空间开发规划中工程地质评价的技术平台，还可期待为其他类似工程地质适宜性评价工作提供借鉴。Abstract: With the development trend of the underground space in the central area of Beijing’s inner city, based on the conventional construction technology of excavation engineering, the analytic hierarchy process is adopted to establish a new suitability evaluation method for engineering geology. The calculated results of this method can be used to estimate the influence of engineering geology condition on the construction and usage of excavation engineering. The proposed method can be used to estubish a technological platform of engineering geology suitability evaluation for the development planning of urban underground space in Beijing. It may provide reference for suitability evaluation work of similar engineering geology.
