沉埋管隧道的施工技术及发展趋势

隧道作为一种更加便捷、安全的穿越江、河、湖、海的交通工程之一，有不受外界气候、风雨、波浪、水流、冰凌、大雾等因素影响的诸多优势。文章介绍了沉埋管隧道在世界各个国家和地区的分布情况及其主要原理和施工工艺，并就其发展趋势作了阐述。

Construction Technology and Development Tendency of Submerged Tubular Tunnel

Tunnels, being one of the transport means passing through rivers, lakes and seas more rapidly and safely, have such advantages as being unaffected by adverse climate, rain and winds, waves and currents, ice packs and heavy fogs. The paper gives a brief introduction to the major principle and technology of construction of submerged tubular tunnels and the present situation of submerged tubular tunnels in various countries and regions in the world. The paper also makes an expounding on the development tendency of submerged tubular tunnels.
