摘要
地震横波反射法和高密度电法是两种常用的物探方法,广泛应用于城市工程地质勘察中的岩土划分、地质构造和特殊介质探测等方面.采用这两种物探手段,在某市工程勘察拒测区进行探测,分析解译横波反射和高密度电法剖面成果,获得了各岩土层电性和地震波速度信息,结合外围工程勘察地层剖面资料,基本查明了测区土层分类和基岩面的起伏情况,为该城市工程勘察提供了科学的地质依据.
Abstract
Earthquake shear wave reflection method and high-density resistivity method are two common geophysical methods,which are widely used in urban geotechnical investigations,such as geologic divi-sion,geological structures and special medium detection.By employing these two geophysical methods,an investigation is conducted in a rejection area of a certain city.The analysis and interpretation of the shear wave reflection and high-density resistivity profiles provide information on the electrical properties and seismic wave velocities of each soil and rock layer.Combined with the stratigraphic profile data from the peripheral engineering investigation,the investigation effectively identifies the soil layer classification and the undulation of the bedrock surface,providing a scientific geological basis for the city's engineering investigation.
