【摘要】 在计算非饱和土地基极限荷载时，考虑其中存在着负的孔隙压力即吸力，由此得到非饱和土地基极限承载力的计算公式。通过一个计算实例说明吸力对非饱和土地基极限承载力影响显著。在实际工程设计时，应根据地基实际情况考虑这种影响。更多还原

【Abstract】 When calculating the ultimate load of foundation on unsaturated soils, it is considered that there is the negative pore pressure,that is the suction, and a calculating formula of the ultimate bearing capacity on unsaturated soils was derived from this. The remarkable effect of suction on ultimate bearing capacity was shown by a calculation example,and this effect should be taken into account in accordance with the actual foundation condition for practical engineering design.更多还原
