1)  Additional inner press
附加内压
2)  additional internal pressure
附加内压力
1.
Based on the concept of additional internal pressure, We revealed that the general suction in unsaturated sand with low moisture content consists of the capillary suction and the additional internal pressure,and the effective stress is decomposed into two parts:one caused by the general suction, and the other caused by the gravity and other external loads.
在引进附加内压力概念的基础上 ,将非饱和砂土中的基质吸力划分为毛细吸力和附加内压力两部分 ,进一步将低含水率非饱和砂土中的有效应力区分为由基质吸力引起的有效应力及由重力和其它外力产生的有效应力两部分 ,基此推导出了基质吸力与抗剪强度之间的关系 ,第一次成功地解释了关于非饱和砂土抗剪强度的Donald实验现象 :非饱和砂土的抗剪强度随含水率降低、基质吸力增大而升高 ,但升高的速度逐渐减缓 ,并当基质吸力超过某一阀值时 ,抗剪强度开始随基质吸力的增大而下
2.
After introducing the concept of additional internal pressure, it is shown that the general suction consists mainly of the capillary suction and the additional internal pressure,and the effective stress should be decomposed into two parts: one caused by the general suction, and the other caused by the gravity and other external loads.
在暂不考虑其它因素引起的基质吸力组成部分 ,而只考虑毛细水作用对基质吸力的贡献的基础上 ,引进了附加内压力概念 ,将基质吸力分解为毛细吸力和附加内压力两部分 ,进一步将低含水率非饱和土中的总有效应力区分为由基质吸力引起的有效应力及由重力和其它外力产生的有效应力两部分 ,基此推导出基质吸力与抗剪强度之间的关系 ,解释了非饱和土的抗剪强度随含水率降低、基质吸力增大而增大且相互依赖关系呈非线性等重要试验现
