今年6月,美国地下空间协会的一批建筑科技人员在堪萨斯城开会研究利用地下空间问题。他们认为,发展用于住宅和商业的地下空间,对于降低能源消耗、减轻环境污染和交通拥挤以及缓和住房的需求均具有重要意义。地下建筑冬暖夏凉,它不仅可以大大降低取暖和降温的能源消耗(据说有的可减少75％以上),可以避开城市地面上日益严重的环境污染和噪音,还可缓和一些地区人多、地少、地面建筑拥挤的状况。去年,美国已建有3,000一5,000套地下住房以及几十个地下图书馆、美术馆、档案室、仓库等。明尼苏达大学土木工
In June this year, a group of U.S. scientists in the Underground Space Society held a meeting in Kansas City to study the use of underground space. In their opinion, the development of underground space for residential and commercial use is of great importance for reducing energy consumption, reducing environmental pollution and traffic congestion, and alleviating housing needs. The underground building is warm in winter and cool in summer, not only can it greatly reduce the energy consumption for heating and cooling (which is said to be reduced by more than 75%), it can avoid the increasingly serious environmental pollution and noise on urban ground and can ease the population in some areas , Less ground, crowded ground construction conditions. Last year, the United States had built 3,000 to 5,000 underground houses and dozens of underground libraries, art galleries, archives and warehouses. Civil Engineering, University of Minnesota
