Abstract

Abstract

Be aimed at negative frictional resistance on the pile sides caused by collapsing in collapsible loess zones, two kinds of methods to reduce negative frictional resistauce were designed, which were to wrap piles with linoleum or with steel casing pipes. The model tests were conducted to contrast the laws of load transfer for the two novel piles in collapsible loess before and after immersion. The test results showed that in the condition of immersion, the piles wrapped with steel casing pipes could efficiently reduce negative friction resistance caused by collapsing; the piles wrapped with linoleum could reduce negative friction resistance of piles to a certain extent.
- collapsible loess,
