英国硕士dissertation资料：临时机场布局

Provisional airport layout
临时机场布局

Figure 36 shows a draft for the provisional airport layout. Runways are spaced at 1050m to allow mix-mode use and also in case of an update to ICAO regulations where 1050m spacing may be sufficient for full independent simultaneous use. (9)
图36显示了临时机场布局草案。在1050米跑道间距允许混合模式更新国际民航组织规定的情况下使用，也其中1050米间距完全独立的同时使用可能就足够了。

Expansion of the airport for future development is possible on land, albeit with large earthworks costs due to the topology, however the benefit of this layout is the potential for expansion into the estuary with further land reclamation. Assessment of shipping routes, dredging routes, etc. suggests some further expansion into the estuary is indeed feasible.
扩建机场未来的发展是在陆地上，但由于拓扑的大型土方工程成本，但是这种布局的好处是的潜力扩大土地复垦进一步入江口。

Port upgrade
端口升级

Given the on-going development of the £1.5Bn London Gateway port project across the Thames at the site of the old Shell refinery, a brief assessment of the financial viability of a port development at the site and of an upgrade to the harbour at Sheerness concluded that a new port development as part of this project was not economically attractive or necessary.  http://ukthesis.org/ygsslwdx/
鉴于网关端口15亿英镑的伦敦横跨泰晤士河的项目在现场的老壳牌炼油厂，一个简短的评估，在现场一个港口发展的财务可行性和升级的希尔内斯港的持续发展得出的结论是一个新的端口作为该项目的一部分发展不是经济上的吸引力还是有必要的。

Transport links
运输环节

The forecast of passengers using the airport is vital to the economic viability of the airport. And vital to that is the ease of access to the airport from around the country. Previous suggestions for an airport on Sheppey have been rejected in part because the economic viability of an airport at distance from London relying predominantly on rail travel. Our transport proposal aims to address this concern with improved road access from above and below the Thames. (12)
使用机场的乘客在机场的经济可行性是至关重要的预测。重要的是易于获得来自全国各地的机场。 Sheppey的机场以前的建议已被拒绝，部分原因是由于主要依靠铁路旅行距离伦敦机场的经济可行性。

Road Access
道路通行

To assess the road options, we have to look into the capacity and demand of the road users. The primary purpose for a road is connecting the certain starting points to the destinations. The considerations of the road users are distance, smoothness of traffic, toll charges, service stops, safe and comfort journey. From the builder side, further considerations are taken into account include capacity, future demand, cost, land, ease of construction, disturbance to local residence and environmental reasons.#p#分页标题#e#
要评估的道路选择，我们必须考虑道路使用者的能力和需求。的主要目的为在道路连接的目标的起点到目的地。考虑道路使用者的距离，光滑交通，长途电话费，服务停止，安全和舒适的旅程。

We define our target road users respectively to Isle of Sheppey. They are from North England (Essex), West (London), and Southeast (either locals or from the Continental Europe).
我们定义我们的目标分别谢佩岛的道路使用者。他们来自英格兰北部（埃塞克斯），西（伦敦），和东南亚（无论是本地人或从欧洲大陆）。

The distance between the Central London and Isle of Sheppey is around 55 miles and the journey time is estimated around 1 hour 30 minutes by car. The existing towns on Isle of Sheppey are Sheerness and Queenborough. Sheerness is a port an important trading centre in UK.

A249 is the one and only road which can access to the isle from mainland Kent at the moment. A249 is dual-carriageway and connected to M2 and M20. A 4-lane (2 on each direction) road bridge ‘Sheppey Crossing’ is connecting the both sides.
“A road connection from A130 and A13 in Essex to A289 and M2 in Kent, Medway- Canvey Island crossing has been proposed in 2008. A road tunnel would be linking Canvey Island and Hoo Peninsula. A rail link would link the Thames Gateway network with the Cross-rail proposal for London. (26)

We are suggesting two options for road access:
我们所提出的建议，道路交通便捷的两个选项：

Option 1
选项1

Assuming the Medway-Canvey Island Crossing scheme is approved:
假设梅德韦肯维岛隧道计划被批准：

• There would be a new road about 30km (approximately) connecting A130 and A13 in Essex to A289 and M2 in Kent plus a tunnel (7.6km) across Thames.
• Eastbound (to East)
• The road is from the intersection on Hoo Peninsula to Sherness with a bridge of 2.3km. The Journey is 12km. Another 5-10km (approximately) road will be running from Sheerness to the airport terminal.

Option 2
选项2

This plan is to upgrade A249 from current 2-lane to 3-lane starts from the intersection between M2/A249 near Danaway up to Queenborough and continues to the airport terminal. Further works required are direct divert roads at the intersection and expansion on current the current bridge at River Swale, ‘Sheppey crossing’. This part of route is about 13km right before reaching Queenborough, and further 5-10km (approximately) to the airport terminal.
该计划是升级A249从目前的2车道，三车道从路口开始之间M2/A249附近Danaway到Queenborough并继续与机场航站楼。

Option 1 benefits the North users a lot. Original route from Benfleet to the Isle is about 90km while with this new road, the distance cut down to about 30km. It is a third of the original. Those travelling Northbound/Southbound (e.g. Dover) will need not to detour via London or M25.#p#分页标题#e#

Sheerness is an important port so the new bridge should not/least disturb the porting ships. The Hoo Peninsula is protected land. Permission and environmental assessment are needed.

Option 2 is the upgrading of current roads in order to smooth the traffic flow.
选项2是现有道路的升级换代，以平稳的交通流量。

The two options are shown in Figure 37.
这两个选项，如图37所示。
