| Abstract: | The spherical cavity expansion theory of indefinite soil mass was introduced,and based on the solutions of octahedral stress and the ultimate bearing capacity of saturated compact sand soil when material was non-linear in high stress state,the formula of pore pressure in non-linear saturated and compact sand soil under the spherical cavity expansion pressure was deduced,and finally the distribution of pore pressure was analyzed |
