摘要
由于城市地下空间开发存在复杂地质风险问题,地下空间探测已成为城市地质调查研究热点.该文以福州新区滨海新城为例,针对中、强风化基岩埋深、断裂分布、孤石分布等地质问题,采用微动探测精细划分了地下空间结构.结果表明,微动探测可有效地划分地层结构、查明强风化-中风化基岩埋深、孤石探测等,为城市地下空间开发利用与风险评价提供有力保障.
Abstract
Due to the intricate geological risks associated with urban underground space development,underground space exploration has emerged as a prominent area in urban geological investigation.In this paper,taking Binhai New City in Fuzhou New District as an example,microtremor detection technology is employed to finely delineate the structure of underground spaces based on factors such as burial depth,fracture distribution,and isolated rock distribution within medium and strongly weathered bedrock.The results show that microtremor detection effectively facilitates classification of formation structures,deter-mination of burial depths ranging from strongly weathered to moderately weathered bedrock layers,and i-dentification of isolated rocks.These outcomes provide a favorable assurance for the development and uti-lization of urban underground space as well as risk assessment.
