摘要
城市地下空间的开发利用是城市可持续发展的必然途径。城市地下空间岩土体可利用性是指对城市地下空间岩土体的工程地质性质进行评价,综合考虑岩土体自身的物理力学性质、水文地质条件,以及地表以下不同深度处的工程种类对岩土体的质量需求。笔者分别探讨了长春市地下空间岩土体在地表以下0~3 m、3 m^15 m、15 m^30 m深度区域内的常见工程种类及岩土体分布特性,并分析了不同深度处的岩土体可利用性影响因素,根据粗糙集理论对长春市地下空间岩土体属性进行了重要性评估,得到具有客观性和可靠性的权重赋值,为长春市地下空间岩土体的可利用性评价奠定了基础。
The utilization of urban underground space is an inevitable path in city sustainable development. The evaluation result of rock and soil mass attribute could be used as rock and soil mass availability in urban underground space. The influence factors of urban underground space availability are not only related with rock and soil mass physical and mechanical characteristics and hydrogeology condition,but also related with their different engineering types. This paper analyzed the characteristics of rock and soil mass and different engineering projects in urban underground space at depth of 0 ~ 3 m,3 ~ 15 m,15 ~ 30 m underground separately. Based on Rough Set theory,the evaluation model of rock and mass attribute in urban underground space was established,and the weight values were obtained,which could be used in the evaluation of rock and soil mass availability in urban underground space.
