Abstract

Research purposes: This paper gives some experiences in railway designing in the condition of having buildings by introducing the designing of railway with having civil air defense marketplace.

Research methods: According to the real construction situation of railway station under civil air defense under the East Straight Street in Haerbin，the analysis and research have been made by adopting the methods of finite analysis and structure analysis on the railway station under civil air defense based on the analysis of initiative underpinning method.

Research results: After two underpinning to marketplace structure，the possible different settlement of 1 .7-2. 4 mm are banished and then the maximal settlement between side walls and pillars of 8. 4 mm is eliminated. In the whole construction，the method assures the traffic in sequence and the business in normal. And it is an effect method to put in practice.

Research conclusions: It is feasible to adopt the underpinning method to marketplace underground in construction. There are many questions to research in design of buildings which are in the condition of having buildings underground and adopt the initiative underpinning technology，and it is the research direction in the following work.
