Abstract:

Based on the field tests of the retaining wall with tenon，strength reduction finite element method had been developed to analyze theoretically limit sliding resistance force of the retaining wall with tenon of 0.0m,0.7m and 1.0m length. The sliding failure mode of the retaining structure with tenon was studied. The sliding resistance mechanism of the tenon of the retaining structure in the soft ground had been researched. The integrated stability safety factor of the retaining structure with tenon was put forward. Research showed: the results of theoretical research could be a good characterization of field test results. The retaining structure with tenon was damaged from sliding into overturning with the increase of tenon length. The application of the strength reduction finite element method to retaining structures limit design is entirely reasonable; this method could be applied to the engineering design of retaining structures with tenon.

Key words: tenon；retaining structure, limit sliding resistance force；field test, strength reduction finite element method
