The problem of strength,liquefaction and failure of saturated sands has always been greatly concerned in dealing with the safety of foundations of hydraulic structures and earth or earth-rock dams against earthquake action.This paper gives out some criteria and methods for their evaluation. The theory of limit equilibrium has been used as a criterion to evaluate the incipient failure condition of the saturated sands under cyclic loading and the corresponding laboratory tests and analytical methods are suggested.The distinction between liquefaction and incipient failure has been clarified.Furthermore,a preliminary scheme of open-type effective stress dynamic analysis method is proposed.Finally,the subjects for further investigation are remarked and the importance of preventive measures to avoid liquefaction and failure of saturated sands is emphasized.

饱和砂土在往返荷载作用下的强度、液化和破坏问题关系到对工程安全的估计,乃是近年来在水工建筑物地基和土石坝抗震防震工作中经常探讨的课题.本文对这些问题提出了一些准则和方法,主要认为极限平衡理论可以作为评价饱和砂土在往返荷载作用下开始破坏的准则,而在此基础上提出了相应的试验和分析方法以及区别液化和开始破坏的不同界限.此外,又根据砂土的结构和压缩特性,初步提出了开敞式有效应力动力分析方案.最后并指出了一些尚须研究和重视的问题.

The problem of strength, liquefaction and failure of saturated sands has always been greatly concerned in dealing with the safety of foundations of hydraulic structures and earth or earth-rock dams against earthquake action. The theory of limit equilibrium is adopted as a criterion in evaluation of the incipient failure state of saturated sands under cyclic loading, and the corresponding laboratory tests and analytical methods are suggested. The difference between liquefaction and incipient failure is clarified. Two types of approach are proposed for evaluation of pore water pressure changes induced by cyclic loading, in one of which their dispersion and dissipation behaviour is taken into account.

饱和砂土的强度、液化和破坏问题是水工建筑物地基和土石坝抗震安全中考虑的重要问题。本文建议以极限平衡作为饱和砂土在往返荷载下开始破坏的准则,并且提出了相应的试验和分析方法。阐明了液化与开始破坏的区别。提供了两种估计饱和砂土在往返荷载下孔隙水压力变化的途径,其中之一考虑了它们的扩散和消散作用。

For the purpose of exposing the influences of stress path on the stress-strain behaviors of earth fill, a lot of experiments were performed in the triaxial shear apparatus by using a variety of stress paths on various specimens of different soil types, involving cohesionless, also cohesive.According to the practical variation of stress distribution in the earth-rock dams, the laws of the stress-strain relationships under the condition of constant stress ratio (σ1/σ3=const.) stress path were emphatically...

For the purpose of exposing the influences of stress path on the stress-strain behaviors of earth fill, a lot of experiments were performed in the triaxial shear apparatus by using a variety of stress paths on various specimens of different soil types, involving cohesionless, also cohesive.According to the practical variation of stress distribution in the earth-rock dams, the laws of the stress-strain relationships under the condition of constant stress ratio (σ1/σ3=const.) stress path were emphatically discussed.An exponential model, which better reflects the results obtained from the experiments under the condition of constant stress-ratio path, was suggested.The application of this model to calculate the stress and displacement distributions in an earth dam during construction period comes to the conclusion that the stress path exerts an important influence on the displacement distribution in earth dam, rather than the stress distribution.In this paper, a comparative work was presented, taking stress path in consideration or leaving it out in the finite element method calculation of earth dams (i.e. comparison of exponential model with Duncan-Chang model).

本文对若干砂性土和粘性土进行了多种应力路径条件下的三轴试验,以揭示应力路径对填土的应力-应变特性的影响。并针对土坝实际应力变化情况,着重探讨了等应力比(σ_1/σ_3比值为常数)应力路径条件下土的应力-应变关系的规律性。提出了较接近于等应力比试验实测成果的指数模型,并用之于研究土坝在施工期的应力及变位分布,得出应力路径对土坝变位分布计算成果有重大影响的结论。本文还将考虑应力路径的指数模型与邓肯-张不考虑应力路径的双曲线模型在土坝有限元计算中的应用作了对比。
