基础托挟技术的起源可追溯到古代,但是基础托挟技术直到本世纪三十年代,美国兴建纽约市的地下铁道时才得到迅速的发展。近年来,由于大型、深埋和地下建筑物的矢量施工,以及对现有建筑物的改建、加层、加大使用荷载等方面的需要,促使世界各国的托换技术又有较快的进展。我国的基础托挟技术的数量与规模,随着建设事业的发展也在不断地增长,而且有很多的创新和特色。本刊将按三部分分期向读者介绍,本期为第一部分。
The origins of basic hacking technology can be traced back to ancient times, but the underlying hacking technology did not develop rapidly until the United States built the New York City subway in the 1930s. In recent years, due to the large-scale, deep-buried and underground vector construction, as well as the existing buildings, alterations, additional layers, increasing the use of load and other needs, prompting the world underpinning technology and faster progress . The number and scale of our country’s base hacking technology are also growing with the development of the construction undertaking and there are many innovations and characteristics. The magazine will be introduced to readers according to three parts, this issue for the first part.
