Abstract

Abstract:

In this paper, comparison and contrast is made among old anchor bolts clearing programs of underground diaphragm wall of Nanning Railway Station station of Nanning railway transit in terms of economy and safety. Theoretical calculation is made on cutting strength, anchoring force between anchor bolt and soil and hoisting force of slot machine, and the stability of underground diaphragm wall is analyzed. In the end, the rationality of the using of slot machine is testified.

Key words: Nanning railway transit, foundation pit, old anchor bolt, clearing
