交通软土地下空间开发工程地质适宜性评价指标体系研究

Study on the Suitability Evaluation Index System of Engineering Geological Requirement in Soft Soil Underground Space Development for Transportation

从地质条件、既有结构以及开发扰动这3个方面重点分析了地形地貌特征、工程地质水文情况、地质构造条件与不良地质情况、地上建筑与地下基础以及施工扰动因素对交通软土地区地下空间开发的影响机理。基于负面清单法指导、筛选规避了重叠因素,提炼出适用于交通软土地区地下空间开发的适宜性评价指标,针对不同交通软土地下空间开发深度层次建立了工程地质适宜性评价指标体系,有利于准确评价交通软土地区地下空间开发的工程地质适宜性。

The influence mechanism of landform features,engineering geology and hydrology,geological structure conditions and adverse geological conditions,above-ground building and underground foundation,and construction disturbance factors on underground space development in traffic soft soil area is analyzed from three aspects:geological conditions,existing structure and development disturbance.Based on the guidance and screening of the negative list method to avoid overlapping factors,the suitability evaluation index suitable for the development of underground space in traffic soft soil areas is extracted,and the engineering geological suitability evaluation index system is established for different levels of development depth of underground space in traffic soft soil areas,which is conducive to accurately evaluating the engineering geological suitability of the development of underground space in traffic soft soil areas.
