摘要：The preliminary design and parametric study of 1400 m partially earth-anchored cable-stayed bridge are described. Static per-formance of this new type of bridge is discussed. Compared with fully self-anchored cable-stayed bridge, its advantages in fin-ished state are summarized. Based on numerical calculation, effects of several structural parameters on static performance are presented.

摘要：The safety of large structures requires adequate foundations, which implies a good knowledge of the geological and geotechnical conditions of the respective ground. In general, that is only possible through engineering geological studies which include proper site investigation techniques, adapted to the nature of the ground (rock mass or soil) and to the associated engineering problems. The paper illustrates the studies carried out for the design of the foundations of Ribeiradio 76 m high concrete gravity dam in a difficult rock mass and of Vasco da Gama bridge, 13 km long, crossing the Tagus River in Lisbon, Portugal, through piles 75 m deep.

摘要：Based on the custom of stone bridge and village, by categorizing and interpreting the relationship between Lufeng bridge （鲁封桥） and Luqiao Village （鲁桥村） in Southern Shandong Province, China, this paper focuses on discussing the dynamic of rural society change in China and the practice of village life world. It provides detailed materials of field research about folk life of stone bridge and village in North China. Here village life world not only includes the folk integration of their everyday life, but also covers local villagers cognitive attitude towards village, such as village history, legend, belief, ritual, clan and other everyday life styles. Expounding and reconstructing of village life world, shows the essential meanings and categories of bridge folklore, it also demonstrates the consequence of shifting connection between stone bridge and village life. Firstly, the crucial context of understanding village life world is still promising. Secondly, folklore fieldwork is an significant part to comprehend the connotation of village life world.

摘要：与纽福戈岛艺术公司的所有艺术工作室一样，位于深水湾的bridge工作室沿用了纽芬兰省传统的盐盒式建筑结构。深水湾一带是纽福戈岛最小的居民区，居民总数只有约150人。

摘要：Ultra-high performance concrete (UHPC) is featured by a compressive strength 5 times higher than that of ordinary concrete and by a high durability owing to the control of the chloride penetration speed by its dense structure. The high strength characteristics of UHPC offer numerous advantages like the reduction of the quantities of cables and foundations by the design of a lightweight superstructure in the case of the long-span bridge preserving its structural performance through axial forces and structures governed by compression. This study conducted the conceptual design of a hybrid cable-stayed bridge with central span of 1000 m and exploiting 200 MPa-class UHPC. The economic efficiency of the conceptual design results of the hybrid cable-stayed bridge with central span of 1000 m and of Sutong bridge, the longest cable-stayed bridge in the world, was analyzed.

摘要：Steel fenders are increasingly used for ship-impact resistance structures in the design of navigable bridges. As an important approach to investigating this anti-impact structure effectiveness to reduce influences of vessel impact, simulation analyses are still not perfect yet. So this paper is intended to discuss several issues related to ship collision simulations, including steel constitutive relationship, connections between steel box and pile cap, contacts definition and friction consideration, and the determination of impact waterlines and angles. Consequently based on two examples of ship-steel fender-bridge structure systems, some conclusions about effectiveness and design of fenders to reduce ship impact are drawn.
