This paper is aimed at determining the effects of the soil characterization on the seismic input to use for seismic assessment. Three different soil profiles have been assembled to represent the stratigraphies found through a proper experimental investigation, carefully described, and alternative seismic site response analyses have been performed. The surface spectra obtained from the seismic site response analysis (SRA) are very different from each other, thus evidencing the importance of carefully describing soil stratigraphy. Furthermore, the comparison among the surface records found for different return periods has shown a limited sensitivity of the SRA to the seismic intensity. 相似文献

ABSTRACTBefore the Second World War it was a cardinal Commonwealth principle that intra-imperial disputes must be kept away from international fora. Yet in 1946 the not-yet-independent India complained to the United Nations about South African legislation discriminating against people of Indian origin. It did so without seeking Britain's approval, and went on to level fierce criticism at Britain's opposition to the UN General Assembly's discussion of the matter.This article explains the circumstances which led to these events; uncovers the divergent responses of the relevant British government departments – the India Office, the Dominions Office, and the Foreign Office – and shows how they were resolved; depicts the way in which Britain's delegation to the General Assembly handled the matter; and discusses the significance and consequences of the dispute for South Africa and for Anglo-Indian relations. 相似文献

This article deals with the finite element analysis of dam with and without fluid-structure, soil-structure and soil-structure-fluid interaction. A two-dimensional direct coupling methodology is proposed to obtain the response of dam-reservoir-foundation system considering fluid-structure and soil-structure interaction simultaneously. The displacement based finite element technique is used to formulate the dam and foundation. The reservoir is modeled by pressure based finite element to reduce the degree of freedoms and there by the computational cost. The responses of dam, reservoir, and foundation with and without fluid-structure, soil-structure and soil-structure-fluid interaction are compared to study the influence of reservoir and soil foundation on the behavior of these respective sub systems. The fundamental frequency of individual sub system decreases with the consideration of coupling effect among these sub systems. On the comparison of the responses of dam, it is observed that the displacement and principal stresses are increased if the effect of reservoir and foundation are considered and the worst responses were observed when both the fluid-structure and soil-structure interaction effects are considered simultaneously. The magnitude and distribution of stresses within the foundation change with the consideration of soil-structure-fluid interaction. Similar to wstresses in the foundation, the hydrodynamic pressure within the reservoir also gets magnified due to interaction effects. The velocity distribution within the reservoir becomes distorted when the fluid-structure and soil-structure-fluid interaction are considered. 相似文献

Lewis Binford’s contributions to field archaeology have been largely ignored in favor of his many contributions to theoretical issues dominating the discipline of archaeology at the end of the twentieth century. We examine Binford’s excavation methods in southern Illinois in the early 1960s and demonstrate how his considered approach served to systematize large-scale site excavation procedures. He adopted the time-honored tool of the salvage archaeologist—heavy equipment—and unapologetically employed it in a fundamentally new way, proving it to be a tool that served the greater goals of archaeological research. We trace the development of field methods and theoretical approaches in two case studies of Illinois archaeology and demonstrate how Binford’s contributions have been incorporated or rejected by subsequent CRM researchers. 相似文献

北魏均田制下产权制度变迁分析 总被引：1，自引：0，他引：1
结合新制度经济学的有关理论,对我国历史上的均田制进行分析是很有意义的。作为国家强制性的制度变迁形式,均田制依靠国家的力量得以推行,为国家建立税收基础,以实现国家租金收入的最大化。但是,在均田制实施的过程中,却遭遇到了来自下层的变通与退出力量,使得均田制度的演进过程又呈现出既定利益结构下的诱致性变迁。 相似文献

Assessment and interpretation of the presence of developmental defects of enamel formation that result from childhood experiences of growth disruption, enamel hypoplasia, is a standard part of almost any systematic bioarchaeological assessment. However, different identification methods lead to different results. This study presents a new method of defect identification that offers a quantitative criterion for establishing defect presence rather than relying solely on observer judgement. It then compares this with a standard field approach to assessing enamel hypoplasia and a non-quantified microscopic approach in order to determine (a) if traditional methods of identifying enamel hypoplasia under little or no magnification offer the same information about the experience of childhood health as methods that examine dental enamel growth microscopically, and (b) the effect of using a quantified criterion to identify enamel hypoplasia. A case study using simultaneously developing teeth in one individual is presented where observations of defect presence are made both macroscopically and microscopically and with and without this novel metric method. The results demonstrate that the chosen scale of observation is a critical variable in identifying linear hypoplastic defects of enamel. Defects that occur in the more cervical regions of a tooth are ‘missed’ by methods that rely on macroscopic observation or the unaided visual judgement of the observer. This finding has considerable implications for the interpretation of reported enamel hypoplasia prevalence. 相似文献
