摘要
古代遗留下来的土筑城墙和护城河因为受外营力作用和土地平整而变得面目全非。为了制定古城保持措施,必须搞清楚古城墙构造和护城河范围。古代城墙与城墙坍塌堆积、护城河内填充物与护城河两岸原生堆积不同,导致它们的电阻率也不同,因此利用地下电阻率分布差异就能够分辨出城墙、城墙坍塌堆积、护城河范围等。这里介绍了利用高密度电阻率法分辨阖闾城古城墙构造和护城河范围的过程,勘探结果被洛阳铲钻探证明正确无误。
The appearance and structure of an ancient city wall made of earth might have been greatly changed beyond recognition through long exogenic or/and earth-leveling processes.It is therefore crucial to gain a clear idea of the original extension of the moat and the structure of the city wall in the protection of the city wall.The electric conductivity of a slacktip deposit is different from that of the original city wall,so is the filling in the moat course from the raw earth along the moat.Their difference in the resistivity is thus effective in distinguishing the structure of a city wall from the extension of a moat.This paper presents a successful case study of the wall and moat of Helv fortress,the result of which has been proved to be consistent with that obtained by an traditional archaeological method.
