摘要

在半饱和条件下存在的负孔隙压力为土壤提供了实质性的“凝聚力”。这种黏聚力在堤防和水坝的动力响应中具有重要意义。本文将第一部分中提出的公式推广到半饱和行为的问题，并假设空气自由进入。本文介绍了1971年地震中圣费尔南多大坝下游溃坝的近似重建。

Static and dynamic behaviour of soils: a rational approach to quantitative solutions. II. Semi-saturated problems

Negative pore pressures existing in semi-saturated conditions provide a substantial ‘cohesion’ of the soil. This cohesion is of importance in the dynamic response of embankments and dams. The paper extends the formulation presented in part I to problems of semi-saturated behaviour with the assumption of free air ingress. An approximate reconstruction of the failure of the lower San Fernando dam during the 1971 earthquake is presented.
