    Abstract:

    A laboratory model test was conducted to reveal the difference of bearing capacity of a pile that stays in the mucky clay and the tip of which enters strong bearing layer (sand) and weak bearing layer (silt clay)respectively.The results show that the mucky clay has the characteristic of strain softening; the stronger the strength of bearing layer becomes, the more the pile skin friction increases. The results can explain why the skin friction of the precast pile in mucky clay should be discounted properly in the case that the pile tip bearing stratum is the 5th layer (weak bearing layer)as stipulated in Shanghai Foundation Design Code.
