Studies for the Urban Structure and the Fortification of Ancient Pompeii

通过对公元79年火山爆发后被掩埋的古罗马城市庞贝城北端城垣的考古调查，阐明了庞贝城的城市起源和城市化进程。1997年的勘察中，设置了三条地下坑道。在西区，确认了两处不同的废城墙遗迹。在防御塔已经被发现的中心区域，目前楼层的底层被挖掘出来。从这次调查中，发现了隐藏在现有地板下的L形墙，这将澄清最初的塔楼设计。现在的地板是堆积的。也确认了比原地面高出50厘米的情况。在塔的地板下以及塔后面通往市区的区域下，发现了一条地下通道。在东区，我们的挖掘证实了古城墙的痕迹，在西区发现了古城墙的痕迹，从遗迹可以追溯到公元前6世纪。1998年的调查集中在城墙和市区之间的区域。通过这次调查，弄清了前一年被发现的地下通道的设置和道路的修建对该地区的影响。在调查的同时，研究人员还对79次喷发的火山机制、自然和人工遗迹、庞贝古城的文字学研究和基于照片图像数据的三维测量。

This study was aimed at clarifying the urban origin and the urbanization process of ancient Roman city Pompeii, buried by the volcanic eruption of 79 AD, trough the archaeological investigation at the north end of its fortification.The 1996 investigation clarified that the inner wall of the fortification was completely lacked in our research area. The function of the concealed entrance of the defensive tower was also researched.In the 1997 investigation, three substratum trenches were set. From the western zone, traces of two different abolished city wall were confirmed. In the central zone in which the defensive tower had already been found, the substratum of the present floor level was excavated. From this investigation, the L shaped wail concealed under the present floor was found, which will clarify the original Tower design. That the present floor was heaped ca. 50cm up from the original floor level was also confirmed. Under the floor of the Tower as well as under the area behind the Tower to the urban side, an underground channel was discovered, In the eastern zone, our excavation confirmed the trace of archaic city wall, as found in the western zone, the construction of which can be dated during the 6th century BC from the remains.In l998 the investigation was focused in the area between the city wall and the urban zone. By this study, the modification of this area caused first by the installation of underground channel which was brought to light in the former year, and second by the construction of a road, was clarified.Alongside these investigations, the researchers made such specific researches as the volcanic mechanism of the 79 eruption, the natural and artifact remains, the philological research of Pompeii and the 3 dimension measurement on the basis of the photo image data.
