砂卵砾石层异常定向排列成因探讨

Discussion on Abnormal Directional Alignment of Sand Gravel

砂卵砾石在自然界中是一种极为常见的地质体,砂卵砾石层的定向排列则在普通地质和工程地质勘察分析工作中有着重要的作用,在断层带上呈定向排列时被认为是该断层活动的重要标志之一。当不同的地质体接触面上有呈定向排列的砂卵砾石层时需要认真分析,通过几个工程实例对此进行了较为详细的分析和研究。

Sand gravel is the very normal geological body,directional alignment of sand gravel layer is very useful in the normal geology and the engineering geological investigation.Directional alignment of fault zone is considered to be the one important indicator of fault activity,when different geological contact surface has orientational sand gravel layer need earnest analysis.The paper analyzes it for reference.
