深基坑工程技术的进步与展望

随着大规模工程建设的发展，我国在深基坑设计施工方面也在不断进步，根据地质条件和各种影响因素，基坑支护形式有多种围护墙和支撑体系可供选择。采用计算机设计结果精确，图形准确，目前已基本达到国际水平，但仍有些问题需要进一步研究和提高，如排桩和地下连续墙的内力及变形的精确计算，地下连续墙二墙合一的计算和逆作法施工等。

PROGRESS AND PROSPECTS OF DEEP FOUNDATION PIT TECHNOLOGY

With the completion of great number of large-scale construction project,design and construction technology of China in deep foundation pits have achieved remarkable development.Variety of retain wall and shoring system is available depending on varied geographical conditions and influential factors.The use of CAD fa-cilitates design accuracy and drawing precision,which has generally met the international standard,even though there are still several problems to be solved such as accurate calculation for piles and continuous underground wall,reverse construction method applied to integrated continuous underground wall,etc.
