Analysis on construction of concrete impervious wall for homogeneous earth dam on granular soil foundation;

The mechanical performance of granular materials has much randomness, The influence of randomness on the constitutive relations for granular materials is studied.

Taking advantage of the research on the granular materials,the constitutive relations of the idealized ballast are derived.

Analysis of self-organized criticality of centrifugal model tests on granular mixtures and earthquake effect;

Based on three kinds of experiments which show that SOC is related to granular nonuniform, we validate the assumption: if the structure can form sufficient restraint on perturbation propagation, which limits the trend of increase in eachportionsensitivity by degrees, and granular mixtures can maintain overall robustness in turn accordingly, a largescale system can show the SOC phenome.

Physics experiments on large scale uniform and non-uniform granular mixtures avalanche were carried out and the results proved that internal cause of SOC effect was most probably the structure characteristics of the system but not the size of granular or the scale of system.

Considering the interaction between bulk solid, structure and its foundation, a systematic finite element dynamic analysis on silo structures on elastic foundations is presented in this paper.

This paper calculates the silo s dynamic response when foundation moves, taking into account the effect of interaction between the bulk solid and the silo wall.

The paper calculates the silo s dynamic response when foundation moves and takes consideration of the interaction between bulk solid and the silo wall.
