挑战
URS Corporation 是一家领先的全方位服务工程、规划、设计和施工公司,其任务是对俄亥俄州马霍宁县的麦凯尔维湖大坝进行全面的结构稳定性评估。该大坝是一座 77 英尺高的混凝土拱形结构,坝顶长度约为 350 英尺,形成一个最大蓄水量为 4,345 英亩-英尺的水库。面临的挑战是确保反复的冻融循环不会因洪水荷载的增加而损害大坝的完整性。传统上,此类分析需要进行广泛的现场调查,以收集混凝土和基岩样本进行实验室测试。然而,这个过程既耗时又昂贵,特别是对于位于偏远地区的水坝而言。此外,创建大量计算机模型并运行广泛的单独模拟以彻底分析所有相互关联的变量,这增加了项目的复杂性和成本。
关于客户
URS Corporation 是一家一流的全方位服务工程、规划、设计和施工公司,拥有近一个世纪的商业经验。 URS 在 20 个国家/地区设有 300 个办事处,拥有超过 26,000 名员工,被认为是大坝工程、设计分析和安全领域的领导者。该公司经常为市政当局、公用事业公司和政府机构(例如美国鱼类和野生动物管理局、美国垦务局和美国陆军工程兵团)进行安全检查。
解决方案
为了克服这些挑战,URS 工程师使用 ANSYS DesignXplorer VT 进行灵敏度和参数研究。该软件使用变分技术 (VT) 方法来评估一系列变量对结构强度的影响,包括混凝土墙和基岩材料特性以及最大载荷假设。该软件使用单个有限元解决方案确定多个参数对整体结构性能的影响。结果以各种格式提供,包括响应曲面图,可提供对设计行为的深入了解,否则使用单独的单次分析运行很难生成这些设计行为。研究很快证实,大坝具有足够的能力,可以针对大范围的假设地基和材料特性重新分配荷载。

IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.
