桃渚城城墙病害初步调研与保护对策探讨

临海桃渚城建于明代,是浙江保存最完好的抗倭卫所城址,全国重点文物保护单位。通过对桃渚城的现存状况进行调查分析可知,城墙目前存在局部垮塌、鼓闪、灰浆流失等病害,其本身的构造缺陷加上降雨和植物生长的共同作用是病害的主要成因。这类问题在东南沿海地区的古城墙中具有一定普遍性。针对这些病害以及桃渚城的构造特点,结合国内一些城墙保护的工程实例,提出桃渚城的保护策略:加强墙体的结构稳定性、加固墙芯填土、增设墙顶防水措施、及时疏改威胁本体安全的植物,可为后续以及同类城墙的保护工作提供参考。

Preliminary investigation of damage to the Taozhu city wall and discussion of a strategy for its protection

The Taozhu city wall, built in the Ming dynasty, is the most completely preserved ancient garrison city wall in Zhejiang, and is a key unit of the protected national cultural relics. Investigation of the current status of the wall shows that major types of damage include partial collapse, bloating, and mortar erosion. The internal causes are structural strength defects and the lack of a waterproofing system; the external factors are rain and plant growth. These problems are common in the southeast coastal areas of China. Based on these factors, the characteristics of the wall and a review of protective measures use for othr ancient city walls, a preliminary protection plan is presented for the Taozhu city wall. Our investigation can be used as a reference for protective measures at other sites.
