Through the analysis on the static load test results of piles of a bridge,some conclusions could be drawn: the quality of slurry would have direct effect on the thickness of settled materials of pile tip and the thickness of slurry skin on piles,and further would have great effect on the bearing performance of bored piles.

Numerical simulation of effects of mud cake and bottom sediment on bearing capacity of bored pile;

Centrifuge model tests on super-long piles with large diameters considering mudcake effect;

Studies on characteristics of mudcake and soil between bored piles;

Through laboratory tests on mudcake and middle soil of bored piles in silt soil,clay and silt in Hangzhou,the influence of mudcake on shaft friction and the difference between mudcake and middle soil of bored piles have been studied.

Experimental study on behavior of soil-structure interface with slurry;

Experimental study on influence of slurry thickness on mechanical behavior of interface between gravel and concrete;
