ABSTRACT One of the most telling artifacts in the 9/11 Memorial Museum is the slurry wall, a vestige in situ of the pre-9/11 World Trade Center complex, preserved under Section 106 of the National Historic Preservation Act. This subterranean 20 meter long section of the perimeter wall that surrounded 4.5 hectares of the Trade Center site was never meant to be seen or tell its story. Made of reinforced concrete,and tied back to bedrock, its job was to hold back the waters of the Hudson River. The wall was a marvel of engineering in its time and on 11 September 2001 withstood untold forces and thus acquired new meaning – the once mute, utilitarian object became a symbol of hope and resilience. The slurry wall no longer performs the work it was intended to – there is another loadbearing structure behind it – but remains in conversation with Mother Nature. The wall weeps, which has catalyzed corrosion of the steel, introduced salts and a host of other material concerns. The complexity of the slurry wall, as an artifact and an architectural element of the Museum that affects its environment, has necessitated collaboration between a diverse group of stakeholders to parse its secrets.

泥浆墙：过去、现在和未来

摘要 9/11 纪念博物馆中最有说服力的文物之一是泥浆墙，它是 9/11 前世界贸易中心建筑群的原址，根据《国家历史保护法》第 106 条保存。这个地下 20 米长的围墙围绕着 4.5 公顷的贸易中心场地，从来没有被人看到或讲述过它的故事。由钢筋混凝土制成，并绑在基岩上，它的工作是阻止哈德逊河的水流。这堵墙是当时的工程奇迹，在 2001 年 9 月 11 日经受住了无数的力量，因此获得了新的意义——曾经沉默、实用的物体变成了希望和韧性的象征。泥浆墙不再执行预期的工作——它背后有另一个承重结构——但仍与大自然保持对话。墙体渗出，催化了钢的腐蚀，引入了盐分和许多其他材料问题。泥浆墙的复杂性，作为影响其环境的文物和博物馆的建筑元素，需要不同利益相关者之间的合作来解析它的秘密。
