在重力式码头扶壁式结构实际工程的基础上,利用结构计算商业软件ABAQUS对重力式码头扶壁式结构立板土压力进行了分析,计算结果表明基于有限元方法得到的扶壁码头两肋间立板土压力与基于麦远俭公式法得到的计算结果趋势相似。根据数值计算结果,对不同回内摩擦角的回填土体以及不同刚度的结构影响下的立板后土压力进行了计算分析,并基于此对立板配筋提出了优化建议,可为后续类似工程的设计计算提供科学参考。  相似文献

洋山港水工码头驳岸工程包括承台结构、承台后方的挡土墙、抛石棱体及内侧倒滤层结构。施工期存在因软土层上回填过高过快失控导致承台和码头位移过大的教训,也存在在回填区范围内监测控制点不稳定、工程协调和控制欠缺等问题。通过采取相应的技术和管理措施,驳岸结构质量控制良好。  相似文献

圆筒重力式码头后方回填区漏砂引起的空洞对码头的安全运营有着重大影响,探地雷达法用于病害探测具有独特的优势。本文结合圆筒重力式码头工程特点,基于探地雷达工作原理,通过matlab编程计算对工程模型进行正演模拟,并结合工程实例对水泥板、吹填砂2种介质漏砂异常区以及水泥板、吹填砂、碎石3种介质漏砂异常区进行探测,通过分析电磁波响应特征并对病害异常区域进行圈定,并采用钻孔及钻孔电视成像、地震映像法验证了探地雷达探测效果。实际应用表明探地雷达法可有效用于圆筒重力式码头后方回填区漏砂引起的病害异常区域圈定,研究成果可为同类项目的病害探测及处治提供借鉴。  相似文献

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.  相似文献

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.  相似文献
