卢顿DART客运系统

Luton has a long history of transportation advancements, with the Luton Airport originally opening in 1938, 并且多年来稳步增长. The Luton Airport presently serves approximately 15 million passengers annually, facilitating travel to over 150 destinations spanning 欧洲, 非洲, 和亚洲. 员工人数约10人,000 employees and indirect support for nearly 18,000个工作岗位, this site is a significant contributor to the UK's economy. As this demand for air travel increased over the years for Luton, so did the need for efficient and seamless connections between the airport and other modes of transportation.

Today the Luton DART (Direct Air-Rail Transit) meets this need by transporting passengers from the mainline railway Luton Airport Parkway to the terminal of London Luton Airport in under four minutes. Operations commenced in 2022 and significantly reduced travel time to and from central London to under 30 minutes. 另外, it efficiently transports passengers from Luton Airport Parkway station to the airport terminal in less than four minutes.

The line replaces an older shuttle bus service, 减少道路挤塞, 汽车尾气排放, and improves journey times for travellers from London St. 潘克拉斯到机场候机楼. It involved building rail tracks, two stations, a large tunnel and a bridge. Our team of expert at Jensen Hughes 欧洲 developed the fire strategy design and tunnel modelling for the new stations and all areas in between.

The development of the Luton DART involved the successful execution of seven key components: the construction of DART Parkway and Central Terminal stations, the creation of an eight-span viaduct measuring 310 meters in length, running alongside the existing rail line and supported by seven piers, the establishment of a 750-meter section of running slab on cut and fill, 与A1081相邻, the implementation of a double tunnel spanning 320 meters along the designated route, and the installation of an 80-meter curved bridge weighing 1,000吨. This curved bridge serves as an integral feature of the new Luton DART fast transit system.

The bridge has a steel frame and carries part of the track over a public road. There were concerns that a car fire in the road could affect the steel structure and, 结果是, the steel would need applied fire protection. In order to address the concerns with the bridge, our expert team used a 结构防火工程 analysis to demonstrate that the bridge’s structure had sufficient inherent fire resistance and did not need applied fire protection, therefore significantly reducing project costs.

There were additional apprehensions for the tunnel considering that a train fire could cause the tunnel to be smoke-logged and prevent train occupants from escaping. 为了减轻忧虑, our multidisciplinary team performed computational fluid dynamics (CFD) to demonstrate that the mechanical smoke fans to be installed along the tunnel roof could maintain a clear path for escape to the outside.

通过彩宝网平台的 结构防火工程 分析和CFD分析 烟的造型, we were able to develop a safe and cost-effective solution for this transportation project and support Luton’s growing needs.
