Ground-borne vibrations induced by mine blasting are typically of low amplitudes, which are not considered a major concern for modern engineered structures. However, historic structures are often considered more vulnerable due to inadequate knowledge regarding the state of construction materials and structural response. Specifically, the construction materials used might be fragile or have deteriorated to a stage that could be vulnerable to such vibrations. Simplistic rule based on peak ground motion parameter has been adopted worldwide for safety assessment, while the frequency characteristics of vibrations are not taken into account. Further, there is very limited study on response of heritage structures to near-field blasting. This article presents a practical structural vulnerability assessment method for mine blast-induced vibrations. In particular, a design response spectrum model is proposed based on close range measurements of nearby mine blasting, which is compared with an existing design spectrum model for far-field mine blasts and a typical design spectrum model for earthquake actions. The method is illustrated through a case study of heritage masonry buildings in Australia. The unique blast data presented and the generalized methodology would be useful to both structural engineers and blast engineers in considering potential effects of blasting on heritage structures. 相似文献

We present the results of six years of archaeological work carried out in Heping Dao, Keelung, northern Taiwan. The site has revealed a rich archaeological record spanning a sequence that comprehends most of the history of Taiwan, including the most salient historical landmarks in it. The study of this long-term sequence of habitation in Heping Dao throughout prehistory to current times, allows us to attempt a historical archaeology of the longue duree of the place that in turn enables the establishment of comparisons between periods and raising of specific questions, among them: the general understanding of cultural transformation along the Neolithic and the Iron Age, and in turn the transition Iron Age/Aboriginal historic times in Taiwan, which in our view has to be observed as a history of continuity rather than of interruptions; the recognition of the Chinese presence in Taiwan in the pre-European period; the implantation of the European colony and its effects on the local populations; the differing material remains and impacts caused by the presence of pre-European Chinese and the Qing occupation; and the potential for a comparison between the European and the Japanese colonial projects as seen in the material record. 相似文献

This study proposes a theory‐based cellular automata (CA) in which CA rules are constructed on the basis of a theory of urban land‐use change and other local conditions. Rent gap theory that describes urban redevelopment and exogenous conditions that reflect urban development are embedded into a CA to simulate changes of land use. The theoretical framework provides a strong conceptual background for the CA simulation. A case study demonstrates the flexibility of the integrated framework for simulating land‐use changes in complex settings. This research aims to help decision‐makers formulate appropriate development plans. 相似文献

四川安岳圣泉寺地藏十王龛像 总被引:2,自引:1,他引:1
本文对四川省安岳圣泉寺中的地藏十王龛像作了详细介绍,论及地藏十五龛像的状况及独特价值.认为其雕造时代应属五代,但表达更为精深.此龛构图的回旋特点,与四川绵阳北山院第9号晚唐地藏十王龛像有接近之处.通过实地调查,本文认为在四川与重庆地区地藏十王题材至少可分为三个环系,即绵阳与资中的晚唐龛像、内江与安岳并大足部分五代龛像、大足所存北宋及南宋龛像. 相似文献

This paper explores the concept of heritage as part of sustainable development planning. Heritage is taken to include both the cultural and natural spheres to incorporate people, activities, landscapes, monuments, landmarks, artefacts, and nature. Heritage planning then involves the sustainable development of the cultural and natural environment to prepare for its stewardship, research, and communication for the benefit of society. This perspective leads to broader questions on approaches to heritage planning where the cultural environment is considered specifically within sustainable development planning just as the natural environment is studied separately in specialised disciplines. The paper proposes that in developing resource‐management plans the effects of cultural resources on natural resources, and vice versa, must be integrated and addressed. Seoul, Korea, an historic metropolitan city that has gone through radical political and economic changes, is examined as a case study. It identifies how the city is integrating sustainability of the contextual association of the cultural and natural environment with promotion of economic growth. 相似文献
