墓与塔——宋墓中仿木建筑雕饰的来源

本文将晚唐至宋代墓葬中的仿木建筑雕饰与隋唐时期的地上建筑——仿木砖塔的装饰相联系,推断宋墓中流行的仿木建筑雕饰最早应是受到地上仿木砖塔建筑装饰的影响。

陕北马头山道教真身（肉身）泥塑像搬迁及保护研究

陕西马头山道教真身泥塑造像是以其身体为主,加入麦秸作局部支撑,裹布上泥而成,十分脆弱,急需搬迁和保护。为此,采用环十二烷预加固、贴布紧固及其底边托换等技术对真身造像进行了临时加固,圆满地完成了搬迁,并开展了展示性保护修复工作。本工作成果对高危造像的保护修复与搬迁具有借鉴作用。     

Mud Brick Metaphysics and the Preservation of Earthen Ruins

In the conservation of built heritage, earthen ruins rank as one of, if not the most, intractable of problems to be confronted. Lacking the very architectural devices originally in place to combat and control weathering, earthen ruins face rapid deterioration without constant remedial and preventive conservation. Often it is the enormous mass of many ancient earthen ruins that explain their persistence; however, even these will collapse over time from differential erosion, or eventually stabilize as formless lumps. The impossible demands of simultaneously preserving architectural form and fabric (materiality) challenge the archaeologist and conservation professional who attempt to manage both for temporary and permanent display.     

A COMPARATIVE STUDY OF STRENGTHENING AND RETROFITTING MEASURES FOR UNREINFORCED BRICK MASONRY MODEL UNDER CYCLIC TESTING

An experimental study on half-scale brick-masonry models with different strengthening and retrofitting measures has been studied under cyclic loading in a quasi-static test facility. The strengthening measures undertaken for the studies axe the horizontal bond beam at the lintel and sill level with a combination of vertical reinforcement at corners and openings. The retrofitting measures studied are grouting with epoxy-sand-mortar and cement-grout-injection with welded wire mesh in the cracked region. The tests reveal that the horizontal bond beam at lintel level with vertical reinforcement is effective in reducing the cracking above the lintel level. The insertion of an additional sill-band signi-ficantly reduces the cracking in walls. The epoxy-sand-mortar techniques for retrofitting of cracked regions prove to be effective enough to restore the initial strength, stiffness and deformation capacity. Although specimen retrofitted with cement-grout-injection with welded wire mesh is effective to regain the ultimate strength yet the brittle failure is observed as the specimen is stressed beyond the elastic limit.     

氢氧化镁-凹凸棒土复合材料的合成及在纸质文献脱酸中的应用

凹凸棒土又被称为“万用之土”,在工业生产中有广泛应用。将其与纸质文献脱酸常用的碱性介质氢氧化镁复合,产生一种新的复合物。经反复研究,确定复合物中氢氧化镁的负载量最多为25%,同时通过透射电子显微镜(TEM)确定了复合物的状态,物性分析表明凹凸棒土是良好的脱酸材料载体,并验证复合物的形成。后将这种复合脱酸材料应用于纸张脱酸,经过对比,发现其脱酸性能优越且脱酸后纸张性能明显增强。     

陕西蓝田水陆庵彩绘泥塑颜料分析研究

水陆庵位于陕西蓝田王顺山下,庵内现存三百余平方米精美绝伦的明代彩绘泥塑,是我国泥塑保存最多、最完整的明代彩绘泥塑群之一。为明确水陆庵彩绘泥塑的颜料使用情况,采用光学显微镜、X射线衍射仪、显微红外光谱仪、扫描电镜-能谱仪和显微拉曼光谱仪对颜料样品进行科学分析。结果表明,除中隔壁背面重妆区域的蓝色颜料主要成分是普鲁士蓝之外,水陆庵彩塑使用的颜料大多为矿物颜料,包括铅丹、朱砂、铁红、氯铜矿、雌黄和云母等。研究结果将为水陆庵后续保护修复提供科学依据,并为丰富关中地区明代彩绘泥塑颜料类型补充科学信息。     

安徽淮北相山渠沟墓群M50发掘简报

2016年2月,安徽省文物考古研究所对淮北市渠沟墓群展开抢救性发掘,实际清理墓葬85座。其中M50为带墓道的单室砖墓,可能是一男二女妻妾合葬墓。M50规模较大,出土大量的模型明器和祭祀类器物。根据墓葬形制和出土器物判断,M50的年代当在东汉前期。墓葬的发掘为研究两汉之际该地区乃至整个江淮流域之间的丧葬习俗提供了重要资料。     

安徽马鞍山雨山银塘东晋墓发掘简报

2009年,安徽省马鞍山市博物馆抢救性发掘了马鞍山雨山银塘东晋墓。该墓是一座带甬道的单室砖墓,已严重破坏,但二十多件随葬品时代特征明显。出土的陶俑佐证了六朝时期男女衣著没有严格界限区分的特点,棺床和祭台构筑形式为研究长江下游东晋"凸"字形砖室墓形制演变提供了珍贵的实物资料。     

Changes in chemical composition caused by water–rock interactions across a strike‐slip fault zone: case study of the Atera Fault,Central Japan

In some cases, water–rock interactions in fault zones can affect radionuclide migration. Here, we analyzed the chemical compositions of well‐exposed fault rocks from the strike‐slip Atera Fault, Central Japan, in order to understand the variability and behavior of major and selected trace elements. The fault zone has a 1.2‐m‐wide, smectite‐rich fault core and paired damage zones that developed within welded tuff on one side of the core and within granite on the other side. The 30‐cm‐wide, kaolinite‐rich fault gouge is developed in granite cataclasite, and it shows indications of the latest fault activity, while the 1.2‐m‐wide fault core appears to be older. Hydrogen and oxygen isotope ratios in the clay‐rich fault gouges, and carbon and oxygen isotope ratios in carbonates indicate that the two major clay‐rich zones formed in bedrock near the surface, consistent with observed deformation structures. Based on chemical analyses, we identified (1) a slight depletion in SiO₂, Na₂O, K₂O, and light rare earth elements at the edges of the 1.2‐m‐wide fault core, (2) a clear depletion in SiO₂, Na₂O, K₂O, and all rare earth elements except Eu in the 30‐cm‐wide fault gouge, and (3) an increase in CaO, MnO, and heavy rare earth elements across the entire 1.2‐m‐wide fault core. Findings (1) and (2) reflect water–rock interactions in the 1.2‐m‐wide fault core and in the 30‐cm‐wide fault gouge that resulted in the formation of smectite and kaolinite. Finding (3) reflects carbonate precipitation caused by the addition of basalt fragments from a nearby site to the 1.2‐m‐wide fault core during faulting, and subsequent sorption reactions of heavy rare earth elements via processes such as complexation with the carbonates.
