硬岩的概念,在其天然层理状态,作为一种结构材料是既古老而又时新。在约旦的皮特拉和埃及的阿布辛比勒就留有古建筑的奇观。这些只是当时建筑师们凭直觉意识的结构实例,它既无计算机可用,也无建筑法规可循,却能道出坚固岩石的完整形式,数千年后仍准确无误。 The concept of hard rock, in its natural layering state, is both ancient and new as a structural material. The wonders of ancient architecture remain in the Petra in Jordan and in Abu Simbel in Egypt. These are just examples of architects’ intuition at that time. They are neither computer-usable nor architecturally compliant, yet they reveal the complete form of solid rock that remains accurate thousands of years later.
