Abstract: In order to analyze the difficulties in the construction of deep foundation pit interlocking pile under high groundwater level and solve the problems occurred in the construction process，taking the foundation pit engineering of Jingzhou shipping － railway integrated transport base as an example，some measures were put out to solve the problems of uneven settlement of guide wall，initial unefficiency construction and floating of steel cage by the means of pile test，geological condition analysis and stand- ard formula calculation． According to the analysis of related problems in the construction of interlocking pile，some effective engi- neering experiences in the construction of interlocking pile under complex geological conditions were summarized，such as soft soil foundation in high groundwater level，sand layer and pebble layer，which has certain reference significance for the construction of interlocking pile under similar conditions．

Key words: deep foundation pit, interlocking pile, car dumper shed, construction technology, uneven settlement
