Application of Microtremor Detection Technology in Underground Space Detection in Fuzhou Binhai New City
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.
