核地球物理和化探综合测量在上海市区工程地质调查中的应用

本文介绍在上海市区断裂构造调查中,核地球物理测量和化探的应用效果。应用α卡、地面伽马能谱U、Th、K和总量(Σ)及壤中气汞等测量方法,采用组合指标推断断裂构造,推断出的断裂构造与地震推断的结果相比较,具有较好的一致性。这些方法经济、快速、有效,有着广泛的应用前景。

THE APPLICATION OF RADIOMETRIC AND SOIL MERCURY VAPOR SURVEY TO THE ENGINEERING GEOLOGIC INVESTIGATION IN THE URBAN DISTRICT OF SHANGHAI

The present paper has recounted the effects of applying radiometric measurement and geochemical exploration to the investigation of fault structure in the urdan district of Shanghai.Various measurement methods such as α-card,gamma spectrometric U,Th,K,total amount(Σ)and soil mercury vapor survey were used,and composite indices were adopted to infer fault structure.The result is quite consistent with that inferred by seismic method.Being economical,rapid and effective,these methods will surely have broad prospects in future.
