山崩可能会随着大雨而来,就像今天在英格兰西北部发生的那样。
洪水已经在坎布里亚郡的登特造成了这样的事故,影响了卡莱尔和利兹之间的火车。
什么是山泥倾泻?
当土壤、岩石和泥土落在铁轨上并覆盖轨道时,就会发生山泥倾泻。这通常是在长时间的大雨之后,地面被水浸透。
山泥倾泻会使铁轨变得模糊,造成铁路的严重中断和延误。火车不可能为了避开铁轨上的碎片而转向,所以我们经常需要改变路线。
我们的专业岩土工程师在英国各地工作,以稳定和修复受损资产,使网络更有弹性,以应对未来的风险事件,如极端天气。

发生山崩时我们该怎么办
在发生这样的紧急情况后,我们会派遣我们的工程师前往受影响地区进行任何紧急工作;我们以前的一些与天气有关的紧急维修工程,包括稳定山坡和修葺切割斜坡。
即使在最初发生山体滑坡后,人们仍会担心,所以我们的工程师和承包商将在开始清除轨道上的碎片之前评估现场和损失。一旦山体滑坡开始移动,就很可能会有更多的山体滑坡。

我们轨道两侧的一些斜坡或插沟需要加固。这项稳定地球的工作需要时间。
2月12日,伦敦东南部的山体滑坡导致铁路关闭,使铁路再次对乘客安全。我们的工程师在早些时候对巴恩赫斯特的情况做出了反应,那里的地面条件与伦敦不同:
The geology of the ground here is referred to as Harwich formation, which means there are lots of layers of silt, gravel and clay.<\/p>\n
Any rain that falls percolates down and when it hits the clay layer, the water can\u2019t go any further, resulting in the saturated soil and a landslip.<\/p>\n
These types of ground conditions are quite unusual for London, where clay or chalk are typical.<\/p>\n
In this case, we were alerted at 4am and implemented a safety speed restriction. One of our engineers visited the site and decided it was unsafe to run trains through the cutting.<\/p>\n
Once the landslip had stopped moving, the site was safe for us starting work immediately, beginning with the clearance of any slipped or unstable trees.<\/p>\n
We decided to make the cutting safe by using H piling, where we drill holes into the earthworks and insert H-shaped steel beams into the ground to essentially build a wall that will prevent slippage.<\/p>\n
Carrying out the work safely requires a line closure but this means we can fix the problem relatively quickly.<\/p>\n"}]" :key="i" :i="i" :title="item.title" :icon-name="item.icon" :description="item.description" :is-expanded="slotProps.activeItem === i ? true : false" @expand="slotProps.handleExpand">
