In this article, a Simulink simulation block with the finite element function is developed on the basis of S-function and implemented as the numerical substructure of real-time dynamic hybrid testing. Thereby, a real-time dynamic hybrid testing system coupling finite element calculation and shaking table testing is achieved. Using the developed system, a shear frame mounted on the soil foundation is tested, in which the shear frame is simulated as the physical model and the foundation is simulated as the finite element model with 132 degrees of freedom. Several cases of the dynamic behavior of soil-structure interaction are studied. 相似文献

本文联系有关实物遗存和考古发现,提出贵州遵义南宋杨粲夫妇合葬墓附近所出石券,其年代并非南宋嘉定十七年(1224年),而是明世宗嘉靖二年(1524年);券石四周所刻用波浪形曲线相连之圆点,并非与天文星相有关之"星纹",而是川渝黔鄂地区宋元明墓葬较为流行之河图;该券并非生墓券,而是葬墓券;券主并非南宋杨粲夫人,而是明代嘉靖初年播州杨氏第二十七世土司杨斌之妻,生前因其丈夫身居三品之高位而被诰封为"淑人",死后皇帝遣官"谕祭旌表"。 相似文献

Understanding how to live successfully within our environment is among the most pressing challenges facing contemporary society. This paper probes the problem based on comparative analysis and discusses the relationship between the spatial–temporal distribution of the Neolithic cultural sites and the geographic context in the Hanjiang River Basin in the south of Shaanxi Province, China. Archaeological studies have identified 175 Neolithic cultural sites in the study area, with a sequence of Laoguantai (14C age 8–7 ka BP), Yangshao (14C age 7–5 ka BP) and the late period of the Neolithic Age (14C age 5–4 ka BP). The total number of archaeological sites, the distribution area and the density all showed an early ascending and later descending trend, but the proportion of the number of archaeological sites in the study area to the corresponding value of the entire Shaanxi Province declined sharply. Spatially, these sites were concentrated on the terraces of the Hanjiang River and its main tributaries with an altitude of 400–800 m. Multiple data were integrated to clarify the critical effects of tectonic and geomorphologic conditions on the distribution of the Neolithic sites. Further comparisons revealed the correlation of Holocene climate change and environmental evolution with the Neolithic cultural succession in the study area that ameliorated conditions to generally promote the development of the primitive culture while degeneration coincided with the culture's transition or interruption. The discussion on the origin of the primitive culture and the temporal–spatial distribution corresponding to the regional culture differentiation sheds light on the complex and dynamic human–nature interaction system during the Neolithic Age, thus emphasising the wider field-based investigation and high-resolution reconstruction works of the palaeoclimate and palaeoenvironment in the future. 相似文献

石棺墓是利用石板或石块制作成葬具,以埋葬死者的一种埋葬形式,它是云南西部地区古代民族常见的一种埋葬习俗。洱海地区是云南发现石棺墓最集中与最丰富的地区,该地区包括今禄丰县、楚雄市以西,洱海以东,金沙江以南,哀牢山以北这一广大地区。发现石棺墓的主要地点有姚安县黄牛山、寨子山,宾川县古底;大理市海东, 相似文献

Stable carbon and nitrogen isotope analysis of 15 individuals buried closed to Bayanbulag site or the Shouxiangcheng fortress in southern Mongolia revealed complex dietary features. Only one individual had a diet similar to that of the pastoral population in northern China, while the others, who had varying carbon isotope values and low nitrogen values, might have been from different agricultural areas. 14C dating results suggest that the earliest interment could be much earlier than the building of Shouxiangcheng fortress recorded in Han texts. Analysis of the burial arrangement further confirmed that these deceased were not buried at the same time. 相似文献

敦煌文书与吐鲁番文书对于“舍”的记载内容存在很大差异,仅就敦煌文书而言,其在不同时期对于“舍”的记载格式也有所不同。敦煌文书与吐鲁番文书记载内容的差异,反映了两地居民在各自特殊地理条件下的居住形态及田地经营方式的不同;而敦煌文书记载格式的变化,则反映出不同政权统治下敦煌地区均田制实施情况的差别。此外,敦煌、吐鲁番文书中的“舍”具有不同的用途,明确这一区别,有助于更加深入地理解中古时期两地居民的社会生活状况。 相似文献

前秦时关中氐人分布的武都是指侨置武都郡。侨置武都郡始于曹魏。曹魏为与蜀汉争夺陇右,将武都氐人迁徙至关中,并先后在小槐里和美阳设置武都郡以进行管理。西晋江统的《徙戎论》反映出此时关中武都氐聚居的地方未置武都郡。十六国初期屠各刘氏和羯族石氏先后统治关中,将大量氐羌迁往关东,因此这一时期在关中侨置武都郡缺乏现实基础。苻健立国关中后,在战略要地宝鸡附近侨置武都郡,是其氐人本位政策的体现。北魏时侨置武都郡始领县级行政单位,统治范围扩大,标志着氐人的关中化,同时它也是太武帝平定盖吴叛乱时分化关中南道氐人的重要战略举措。西魏北周立国关中后受政区滥置影响,武都郡领县减少。隋开皇间侨置武都郡在当权者废郡、保留州县的地方行政政策的影响下消失于历史舞台。 相似文献
