伦敦政治经济学院dissertation范文(London School of Economics and Political Science)：机场建设应注意哪些问题？
Isle of Sheppey Airport
谢佩岛机场
Military zones and restricted areas
军事区和限制区
Construction on military zone and restricted areas should be avoided as these are important areas for HM Armed Forces and/or are restricted for various other reasons (Figure 14). These areas should be also avoided by aircrafts.
HM武装部队和/或其他各种原因（图14）限制，这些都是很重要的领域，军事禁区和限制区的建设应避免。这些地区也应避免飞机。
Shipping and Dredging Routes
航运及疏浚路线
These areas do not effect or limit the flight routes unlike the previous two military zones and bird flight paths, however, they limit the area available on the sea therefore these areas and routes should be avoided when selecting the location for construction of the airport.
这些领域不影响或限制不像以前的两个军事区和鸟类的飞行路径飞行路线，然而，他们限制在海面上，因此这些地区和路线时，应避免选择的位置为机场建设面积。
These areas include precautionary areas, major and minor shipping routes, fairways, ferry and dredging routes (Figure 14). It is worth mentioning that having the dredging route in the area can be advantageous in carrying materials to the offshore construction site, or an emergency route when needed.
Fishing areas and obstacles
钓鱼区和障碍
Figure 15 below shows the obstacles in the area around Isle of Sheppey. The area of construction should ideally avoid these as removal of many of them can prove to be economically and/or socially costly. As can be seen there are no obstacles present in the area of construction. However, in the case of future expansion of runways, there may be obstacles that will have to be removed before off-shore construction can commence; these include:
下面的图15显示了在谢佩岛周围区域的障碍。理想情况下，建筑面积应避免这些，去除他们中许多人可以证明是经济和/或社会代价高昂的。
• Off-shore lamp, located in the north-eastern edge of the runway
• General wreck, located in the north-eastern edge of the runway, which is referred to as a point wreck, possibly referring to a relatively small wreck. Unfortunately no detailed information on how significant this wreck may be is available and further investigation of the site is needed once the airport expansion is in planning or early construction stages.
It is also worth mentioning that there are no significant obstacles that may be problematic in case of expanding the runways further in the sea in order to meet the demands in the future.
这也是值得一提的是，不存在重大障碍，可能是有问题的情况下，进一步扩大跑道，以满足在未来的需求在海。

Flight path management
飞行路径管理
This feasibility study does not assess in detail the requirements for flight path planning. It is clear however that incorporation of flight paths for a new airport in the Thames Estuary is possible, without excessive modification or disruption to flight paths for the current major airports. The following figure shows current activity within a 24 hour period for London airports: http://ukthesis.org/ygsslwdx/
本可行性研究并没有详细评估飞行路径规划的要求。但是很显然，成立一个新的飞行路径在泰晤士河河口机场是可能的，没有过多的修饰，或为当前的主要机场飞行路径中断。下图显示了当前活动在24小时内为伦敦机场：

Bathymetry and Topography
水深测量和地形
This section briefly assesses the ground level above and below the Thames at the Isle of Sheppey site considered for our project.
本节简要评估的地级以上及以下的谢佩岛的网站考虑我们的项目泰晤士河。
Bathymetry
测深
The bathymetry of the area is important as the runways of the airport will be built offshore; therefore it is beneficial to keep the construction cost of the man-made peninsula as low as possible by choosing an area with lowest water depth and flattest seabed. This will not only lower the cost of materials used to build the artificial peninsula, it is environmentally more friendly, easier to build and will take less time to construct. Figure 17 shows the bathymetry of the area. It can be seen that the depth of seabed is within 10 meters throughout the project area, and it only passes a single contour line, meaning that the area of the seabed is reasonably level.
水深的区域非常重要，因为该机场的跑道将建成海上，因此它是有利于保持尽可能低的建设成本的人造半岛选择最低的水深和海底平坦的区域。这不仅会降低成本，用于构建人工半岛的材料，它是更环保，更容易建立，并会采取更少的时间来建构。图17示出的区域的地形。可以看出，海床的深度是10米范围内整个项目区，只通过一个单一的轮廓线，这意味着海床的面积是合理的水平。
