摘要
介绍了无限土体中球孔扩张理论,以及在高应力状态下,考虑材料非线性时紧密砂性土的八面体应力及极限承载力解答,推演出了在非线性饱和紧密砂土内,球孔扩张压力下的孔隙压力公式,并分析了其分布特性。
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
