复合土拱新技术及其在城市地下工程中的应用

城市地下空间的开发正起到愈来愈重要的作用，并逐渐形成了一种空间、地面和地下三维一体化的城市新型建筑体系。在这种体系中，地下和地面建筑之间的地基处理是一个十分棘手的问题。结合工程实例，介绍一种复合土拱新技术能够有效地处理这类问题，该技术在今后城建领域中有一定推广价值。

A new compound arching technology and its application to urban underground works

The development of urban underground space is playing the more and more important role. A new type urban architecture system taking space, ground surface and underground as 3D integralization is being produced gradually. The treatment of foundation between underground works and surface buildings in this system is a very troublesome problem. In combination with the specific engineering project, an introduction to a new compound arching technology for effectively tackling this type of problems is made. This technology is of generalized value to the urban construction in the future.
