1.Study on Soil-structure Interface Model Based on Potential Energy Dissipating Principle and Its Application
2.Dangerous situations occurring in levees and their foundations,side beaches in flood periods include infiltration,piping,soil flow,quicksand caused by direct scouring of seepage,leakage chink,leakage due to structures passing through levees,landslide,bank caving,overtopping of levee,etc.
3.In order to reasonably compute the bulk-solid lateral pressure,the pressures predicted by Rankine and Coulomb formulae are compared with those by experiments,the formulae of the Appendix C of Code for Design of Reinforced Concrete Silos(GB50077?2003) are analyzed and verified;
4.(2) FMR data show that the film of 5.2 ML has two magnetic phases, implying a transition state from superparamagnetic nano-cluster structure to continuous film.
5.Abstract: The secular equations of Rayleigh waves in a poroelastic half-space soil are developed by analyzing dynamic equation and continuous equation of poroelastic soil.Ravleigh surface wave dispersion characteristics and its displacement as well as liquid pressure distributions in saturated half-space soil are discussed.
