海岸线弹性对安全铁路至关重要。
It's something we’ve been working hard to improve on the south coast in recent years.
Three years ago, Network Rail turned detective to tackle the challenge of fixing a storm-damaged seawall at Dover to better understand the condition of the area before the incident.
It came two years aftera section of railway fell into the sea in Devonfollowing stormy weather. We reopened this stretch of the railway for passenger services in just eight weeks.
发生了什么
在2015年圣诞节，一场巨大的风暴损坏了德文郡莎士比亚海滩后面的海堤，在它上方的铁路。在几周后，损害停止了多佛与福克斯通之间的火车。
到2016年2月，我们使用了一系列技术来研究墙壁和支撑铁路的结构，包括来自无人驾驶飞行器的激光调查。
亚搏彩票软件官网网络铁路有许多维多利亚人的结构记录，而是南部铁路 - 从1923年到1947年存在 - 并没有在1927年在该网站上进行的工作中保留了许多文件。
Engineers investigated the structure itself with bore holes and trenches, and combed through local newspaper archives and online videos for more information.
Steve Kilby, then senior programme manager at Network Rail, said at the time of the research: “We are the sixth company to own this stretch of railway since it was built in the 1840s, and the record-keeping of some of our predecessors means we are still finding out how this stretch of railway was built.
“如同传统工程，我们对这个项目的第一件事之一是研究现场的历史，建立在此发生的事情的图片。
“What is rapidly emerging is that, while the original viaduct was well built, the work that was done in the 1920s was not what we would have hoped.”
我们发现了什么
The railway on Shakespeare Beach was originally raised on wooden trestles, with the waves breaking on the beach below.
In 1927, the Southern Railway constructed the seawall alongside it, leaving room for a new set of tracks. They then dumped many thousands of tonnes of chalk around the viaduct, encasing it and building the railway on top. This was how it stayed until the storm of Christmas 2015.
在圣诞节期间，莎士比亚海滩重建铁路和一部分海面墙的项目立即开始，成本为39.8亿英镑。
It took:
- 超过90,000吨的摇滚盔甲被驳船运往多佛，到达港口和后者在驳船上锚定近海。
- A railway rebuilt on a 235m viaduct supported by 138 columns, rock armour arranged along the beach to protect it and the cliff face behind it from the power of the sea.
- At its peak, more than 1,000 people worked on the project at Dover, with about 150 working on the beach works and the footbridge.
