中文摘要：

新加坡地少人多,人口密度已接近10000人/km2,土地资源严重不足。为此,新加坡政府对其城市地下空间的开发给予了高度重视。从20世纪80年代开始,新加坡先后开发建设了一系列适应其发展水平的地下空间工程,如地铁、地下商业街、地下停车场、地下管网系统、地下储存库、大型地下公共空间等。其地下空间工程的开发,无论是在理论知识还是技术实践方面,都取得了令世人瞩目的成绩。本文介绍新加坡一些典型地下空间工程案例,探讨其在工程建设过程中所遇到的主要技术难题和所取得的科技攻关成果,从而汲取其宝贵的工程实践经验。结合中国当前一些大中城市地下空间开发利用的现状,提出几点建设性意见。

英文摘要：

Singapore is a country of small land but large population. The population density is close to 10000 per square kilometre. With a severe lack of land resource in Singapore, the government pays a great attention to the development and utilization of the urban underground space. From the 80＇s in the 20th century, a series of underground space projects in its technical and developmental level have been completed in Singapore. For example, the metro, the underground commercial street, the underground parking, the underground pipe network system, the underground storage cavern, the large public underground space. The development of underground spaee projects in Singapore has made a remarkable progress both in theory and in practice. The paper first reviews some successful underground space projects and then discusses the technical difficulties encountered in the construction process. The purpose of the paper is to highlight some valuable experiences in both theoretieal and practical fields in the urban underground projects. Within the context of the current urban underground space development of large cities in China, some suggestions are made.
