| Abstract: | Based on results of field measurements,the mechanism of interaction between high|rise building superstructure,foundation and cobble|stone subsoil is discussed.For calculation of subsoil reactions which is the critical problem of interaction between high|rise building superstructure,foundation and cobble|stone subsoil,the weighted residual method is first used to calculate value and distribution of subsoil reactions on the basis of structural continuum.The program for calculating subsoil reactions is coded in FORTRAN and quantitative analysis of a variety of influencing factors which affect value and distribution of subsoil reactions are carried on. |
