| 摘 要： | 不同岩石在相同风化环境条件下的抗风化能力不同。如何评定岩石的抗风化能力是近年来人们十分关注的研究课题之一,因为它对岩石风化机理分析和石质文物长期保护研究有着重要的科学价值。位于浙江省衢州市的古城墙小西门建于明代晚期。小西门城墙的岩石砌块有多种岩性,它们之间的风化剥落深度相差较大。利用三维激光扫描仪测量了小西门某特定研究区中包含多种岩性的岩石砌块的风化剥落深度,并以此来评定不同岩性岩石的长期抗风化能力,以给出相应的排序。在现场还发现,与所研究的多数岩石砌块相比,被古人用作为古城墙各砌块之间勾缝的黏合材料蛎灰的抗风化能力更强。

| Abstract: | The abilities of different rocks to resist weathering in the same weathering condition are different. How to assess the ability of rock to resist weathering is one of the research topic of great concern in recent years, which has important scientific value for analyzing weathering mechanism of rocks and long-term protection of rock culture relics. The Xiaoxi gate wall of Quzhou ancient city wall was built in late of Ming dynasty(1368～1644A.D.).There are a variety of lithologies in rock blocks of Xiaoxi gate wall. The differences in their depths of surface recession are also large. The three-dimensional(3D)laser scanner is used to measure the depths of surface recession of rock blocks with different lithologies in a particular study area on Xiaoxi gate wall. Based on the measure data, the long-term abilities of different lithologic rocks to resist weathering were assessed and the corresponding sort is attained. It is also found that compared with the rock blocks studied, the ability of shell-limes motar adhered between blocks are stronger. |
