- Abstract:
- In view of collapsible loess foundation in Zhengzhou—Xi’an passenger—dedicated lines，this paperanalyses the properties of long—-short—·pile composite foundation under the embankment load with finite ele··ment method to reach load transmission on pile in long—short—pile composite foundation，Mohr—Columnelasto—plastical constitutive model for soil and piles．The multi—stage filling by using life and death elementtechnology is stimulated．It shows that the influence of parameter of long pile on long—short—pile compositefoundation is more than the influence of short pile．The results are used to improve and to establish the long—short—pile computation theory for the subsidence of composite foundation with practical distinct meanings．
