关于客户
本案例研究中的客户是 One Financial Center 的所有者，这是一栋位于波士顿市中心的 46 层办公楼。该建筑是该地区较大的建筑之一，地下有两层，垫式地基位于致密的粒状土壤上。该建筑靠近中央动脉/隧道项目，特别是 100 英尺深的隧道挖掘，引发了人们对建筑稳定性和安全性潜在影响的担忧。该建筑的业主向中央动脉/隧道项目的项目经理 Bechtel/Parsons Brinckerhoff 寻求帮助，以解决这些问题并确保建筑及其居住者的安全。
挑战
中央动脉/隧道项目，也称为“大挖掘”，是马萨诸塞州波士顿的一项大型工程，旨在取代 90 号州际公路。该项目涉及建造一条新的 7 英里、8-10 车道的道路和各种立交桥，其中大部分将建在城市地下 70 英尺处。然而，由于该项目靠近波士顿市中心一些最大和最古老的建筑，因此带来了重大挑战。 One Financial Centre 就是其中一栋这样的建筑，这是一栋 46 层的办公楼，距离 100 英尺深的隧道挖掘仅 25 英尺。该建筑的业主担心挖掘工作对建筑稳定性的潜在影响。挖掘过程涉及“脱水”步骤，即从挖掘地点和周围土壤中除去水。这可能会导致地面压缩，从而可能导致建筑物沉降、结构应力和损坏。
解决方案
为了解决这些问题，项目经理 Bechtel/Parsons Brinckerhoff 寻求 Weidlinger Associates, Inc. 的帮助，对排水效果和深部开挖进行了研究。该解决方案涉及使用 ANSYS/Mechanical 软件对现有建筑结构/基础、隧道施工、相邻建筑物和地面之间的相互作用进行模拟。该软件使团队能够模拟隧道施工 13 个不同阶段的建筑条件。通过这样做，确保了建筑物和施工现场的安全，并减轻了业主和占用人的担忧。使用 ANSYS/Mechanical 软件可以全面了解挖掘对建筑物的潜在影响，从而可以采取主动措施来防止任何损坏。

Intelligent Building Automation System and Energy Saving Solution
One of the most difficult problems facing the world is conserving energy in buildings. However, it is not easy to have a cost-effective solution to reduce energy usage in a building. One solution for saving energy is to implement an intelligent building automation system (BAS) which can be controlled according to its schedule. In Indonesia a large university with a five floor building and 22 classrooms wanted to save the amount of energy being used.
