The Study on Vertical Structure Characteristics of Ground Substrate in Nan'ao Street,Shenzhen
Ground substrate survey can provide a scientific basis for the local economic sustainable development,rational resource utilization,and ecological environment protection.This study focused on the Nan'ao Street in Shenzhen as the study region,conducting a zonal survey based on rock weathering degree and vegetation coverage.The primary objectives were to investigate the vertical structure characteristics of ground substrate in low mountain and hilly areas,as well as in coastal Quaternary sedimentary areas,and to explore suitable methods for the ground substrate survey in Shenzhen.The following two understandings are obtained:(1)By selecting sampling points and measuring exposed profiles,we determined that the vertical structure of the ground substrate in the weathered crust area of low mountain and hills is mainly characterized by bedrock covered with a thin weathering crust,with the topsoil primarily consisting of loam within a thickness of 1 meter and the underlying bedrock primarily consisting of magmatic rocks.(2)By organizing existing drilling data,we ascertained that the vertical structure of the ground substrate in the coastal Quaternary sedimentary area is mainly characterized by bedrock covered with clay,and bedrock covered with sandy soil and clay,with some areas covered by artificial fill.The thickness of the soil layer is mostly within 20 meters.This study fills a gap in the field of ground substrate survey in Shenzhen,providing a foundation for understanding the interrelationships between ground substrate and other natural resources and environmental factors,and offers reference technical methods and suggestions for the follow-up ground substrate surveys in Shenzhen.
