<正>邮轮经济是由于邮轮产业的运行与发展而推动与拉动相关产业的发展,形成多种产业共同发展的经济现象。邮轮码头根据其重要性可分为母港码头、停靠港码头与小码头。邮轮母港的节点经济特征,能给抵达、停靠、离开邮轮码头带来各种消费和收入。研究表明,邮轮母港的邮轮经济收益是停靠港的10~14倍,邮轮经济对邮轮母港所在区域的经济具有强大的推动力。 相似文献

巴拿马Amador邮轮码头项目场地存在深厚软黏土地层。为了评估地基剩余沉降,基于恒载期间观测数据,采用双曲线法、三点法、Asaoka法预测沉降。针对三点法中3个等间距沉降点难以确定的问题,以最小曲率半径入手,合理定义了3个沉降点。选取5个典型的时间-沉降曲线,对观测点的地基沉降开展了对比分析。得出如下结论:1)双曲线法预测的沉降通常会偏大,随着沉降观测时间的增加,沉降预测的准确度会随之提高。2)Asaoka法预测沉降值与稳定值相近,但小于最终稳定值,显然会使地基沉降偏不安全。3)三点法沉降预测结果大于Asaoka法且低于双曲线法,更接近于稳定值。4)3种沉降预测方法均具有简单、实用的特点,预测的剩余沉降均小于150 mm,满足项目沉降设计要求。 相似文献

对于软弱岩层中的打入桩,目前尚无公认的方法评估桩侧阻力。针对巴拿马Amador邮轮码头航站楼嵌岩钢管桩基础,开展了9组桩基动力测试,采用波动方程分析方法获取桩侧阻力。研究了地层中桩侧阻力分布规律、岩层中桩侧阻力与单轴抗压强度的关系。得出如下结论:1)侧阻力分布曲线均呈抛物线形式,可以明显区分出软黏土、粉质砂土、强风化岩、中风化岩4个地层。将曲线跌落后的部分定义为嵌岩段,据此得到桩A-4嵌岩深度为6 m、其他桩嵌岩深度为4 m,均满足设计最小嵌岩深度3 m的要求。2)岩层桩侧阻力-抗压强度(UCS)曲线均呈指数分布,而非线性分布。3)软弱岩层中,侧阻力起主导作用。同一UCS值,泥质粉砂岩中桩侧阻力明显大于玄武岩。4)随着UCS增大,岩体的自稳能力逐渐增强,摩擦系数逐渐转变为影响侧阻力的主导因素。UCS增大到一定数值后,桩侧阻力趋于稳定。5)获得了岩层桩侧阻力-抗压强度关系式,为估算场地岩层中桩侧阻力提供了依据。 相似文献

如果吹填物为砂质,而吹填区域为淤泥层,传统吹填施工很难解决吹填过程中吹填物对吹填区淤泥的破坏问题,会造成大量淤泥集中,给后续地基处理施工造成极大困难。如果吹填区域淤泥层过厚,而吹填施工速度过快,传统吹填施工还有可能造成吹填区失稳。结合巴拿马科隆集装箱港口(PCCP)工程,利用边坡稳定理论,探讨分层区块化吹填在超厚淤泥底质吹填区的应用,并提供一种区块化分层吹填的施工工艺,供相关工程参考。 相似文献

This paper quantifies likely changes in greenhouse gas emissions which contribute to anthropogenic climate change, resulting
from the expansion of the Panama Canal and the consequent increase in ship-borne commercial transportation from east Asia
to the US east coast. Ocean transportation offers higher fuel economy and lower pollutant emissions compared with land transport.
Additionally, truck and train transportation of cargo along the US land bridge threatens to overwhelm existing highway and
rail systems and limit economic growth. The alternate transportation route for easterly transit of the Panama Canal will reduce
overland traffic congestion and enhance economic development by maintaining freight flow efficiency. 相似文献

The Panama Canal is currently in the process of a major expansion effort. After the new set of locks is opened in 2016, significantly larger ships can traverse the Canal. The current lock system has been in place for over 100 years, even though the size of ocean-going vessels has expanded considerably. One impact is on Panama’s maritime cluster. It is expected that the expansion will result in greater demand for many of the goods and services provided by the cluster. This article examines the economic impact of the Canal expansion on Panama’s maritime cluster. Clusters of economic activity can result in economies of agglomeration and supply chain network effects. Without these economies and network effects, clusters would not have a competitive advantage over businesses that are not in a cluster. It is expected that with a larger cluster, both agglomerative economies and network effects will increase. But, which cluster components will grow and which will not be affected to a great extent? To what extent will bottlenecks appear? These are some of the questions that this article addresses. 相似文献

This article is part of a special issue that provides insight into global conservation science by analyzing a 5-year, $12.5 million global marine conservation science and policy program. In this article, we summarize the development of the program in Coiba Island in the Gulf of Chiriquí Panama, and the Galapagos islands of Ecuador, both part of the Eastern Tropical Pacific Seascape. In Panama, the history of Coiba island as a federal penal colony shaped the process and outcome of the program. In the Galapagos, the unique science history of the islands and subsequent international recognition influenced the outcomes of regional marine managed areas. 相似文献
