    Analysis of the Change in Groundwater System with Tunnel Excavation in Discontinuous Rock Mass
    Jung-Wook Park,Chung-In Lee
    2011, 30(S2): 1073-1079.  DOI: 10.3969/j.issn.1674-0696.2011.supp2.001
    摘要 ( )   PDF(1214KB) ( )  
    In this study,a 2-D finite-element analysis,using the SEEP/W program,was carried out to estimate the amount of groundwater flowing into a tunnel,as well as the groundwater tables around wetland areas during and after tunnel excavation through rock mass. Four sites along the Wonhyo-tunnel in Cheonseong Mountain ( Gyeongnam,Korea) were analysed, where the model domain of the tunnel included both wetland and fault zones. The anisotropy of the hydraulic conductivities of the rock mass was calculated using the DFN model,which was then used as an input parameter into the continuum model. Parametric studies were performed on the influencing factors to minimize uncertainties in the hydraulic properties. Moreover, the volumetric water content and hydraulic conductivity functions were applied to the model to reflect the ability of a medium to store and transport water under both saturated and unsaturated conditions.

    Risk and Probability Considerations in Design of Major Infrastructure Systems
    A.H-S.Ang
    2011, 30(S2): 1084-1089.  DOI: 10.3969/j.issn.1674-0696.2011.supp2.003
    摘要 ( )   PDF(398KB) ( )  
    Significant uncertainties are invariably present in the design of major infrastructure systems such as long-span bridges and other critical systems. In this light,the safety and reliability of the built system cannot be ensured with certainty or complete confidence; there is some probability of non-performance or failure and,therefore,some measure of risk ( the product of the failure probability and its adverse consequence) . For practical purposes,uncertainties may be classified into two broad types-the data-based type ( known as aleatory) and the knowledge-based type ( known as epistemic) ; the former can be assessed through observed data,whereas the latter often requires judgments for its assessment. The thrust of the paper is to present the systematic analysis of the two distinct types of uncertainty and to generate the pertinent risk-informed information with suggestions for determining conservative ( i. e. ,risk-averse) safety levels for the design of major infrastructure systems. The approach is presented for the safe design of major infrastructure systems under seismic loading,and illustrated numerically with the evaluation of a cable-stayed bridge in Korea including its minimum life-cycle cost design.

    Overcoming the Logistical Constraints of Ultra-Long Undersea Tunnels
    Gareth Mainwaring
    2011, 30(S2): 1121-1126.  DOI: 10.3969/j.issn.1674-0696.2011.supp2.009
    摘要 ( )   PDF(305KB) ( )  
    The construction of any very long tunnel is benefited by the provision of staging points along its route,but this is not usually possible for undersea tunnels. For transportation tunnels,for railways or highways,the life safety and ventilation requirements for the permanent works,as well as the construction logistics,need to be considered. These constraints can be overcomed by using proven technology from another field of engineering,the off-shore structures that have been employed in the oil and gas industry. These major off-shore structures can be located in deep waters,and can provide intermediate staging points for tunnel construction which also provides the benefit of accelerating the overall construction programme. The paper discusses how these structures can be employed for the benefit of major undersea crossings that have been identified around the world,and particularly in China.

    Marine Concrete Structures
    T.O.Olsen
    2011, 30(S2): 1138-1145.  DOI: 10.3969/j.issn.1674-0696.2011.supp2.011
    摘要 ( )   PDF(1068KB) ( )  
    When properly odesigned and built,the offshore concrete structures do a very good job for their owners,often in harsh environments like the North Sea or the Arctic. Most of these structures are serving the oil and gas industry. A skill has been developed for designing and building these severely loaded,heavily reinforced structures,including the skill of integrating design and construction properly,and understanding the importance of good construction management. There are numerous more ordinary concrete structures in the marine environment near the shore,such as docks and bridges,that have been erected over a period of more than a century. The experience gained from the design and construction of these structures may be utilized in new applications. In particular the application of traditional concrete platform technology to make ultra long subsea tunnels feasible is described. It is demonstrated that the technology is available and known; many of the elements required have been used before.

    Fatigue Design Criteria for Welded Bridges in the U. S.
    John W.Fisher
    2011, 30(S2): 1152-1158.  DOI: 10.3969/j.issn.1674-0696.2011.supp2.013
    摘要 ( )   PDF(1058KB) ( )  
    Fifty years ago,fatigue design was not considered a serious bridge performance issue in the US. Fatigue design utilized the concept of limiting the maximum stress at details by using the R-ratio of minimum/maximum stress and an assumption that the fatigue limit occurred at 2 million cycles. The HS-20 design truck was used for specific cycles based on the type of road and the average daily truck traffic ( ADTT) . Fatigue cracks were observed to develop in steel bridges in the late 1960’s and early 70’s. This development and the results of large scale beam tests on welded details that were carried out between 1967 and 1987 provided a statistically sound data base and established that stress range alone was the only statistical significant design stress. The fatigue provisions adopting stress range were changed by AASHTO in 1974. This meant that only the live load cyclic stress was important. The basic fatigue resistance curves provide a log normal lower bound design basis for fatigue life that is used world wide today. Experience with steel bridges also showed that a rule adopted after WWII which avoided welding to tension flanges,has resulted in extensive web gap cracking from out of plane distortions. During the last decade these small web gaps have resulted in unanticipated brittle fractures as a result of tri-axial stresses even in the absence of fatigue crack growth.

    摘要 ( )   PDF(1024KB) ( )  
    Europe,Canada and the United States have been developing new probabilistic limit States Bridge Design Specifications, the Eurocode,the Canadian Highway Bridge Design Code ( and the earlier Ontario Highway Bridge Design Code) and the AASHTO LRFD Specifications for Bridges ( AASHTO LRFD) . This paper summarizes the seven - year long process that led to the decision to develop the AASHTO LRFD,the objectives,and the draft review process culminating in adoption in 1993. It then describes the implementation and further development during the decade since,and presents an evolving plan to continue development of the limit states specifications for design and rating of bridges.

    摘要 ( )   PDF(323KB) ( )  
    提出了一种适用于跨径1500 m 左右斜拉桥的原创设计方案,即“部分地锚交叉索斜拉桥”,其主要特点是将 长索交叉并锚固于地锚,使长索不对主梁产生水平压力。研究表明该方案具有以下显著优势: 大幅度降低了斜拉索 引起的主梁水平压力; 交叉索有效提高了跨中区域的刚度; 由于交叉索提供了双重竖向支撑,水平力又相抵,因此长 索倾角可以适当减小,塔高可以降至L /5. 5 左右; 长拉索在跨中区域形成索网结构,有效改善了长索的气动性能。
