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。

The author deduced an ideal linear equation relating the maximum densityof sandy gravels under vibration to the similar gradation modulus, and extra-polated the maximum density of large sized prototype sandy gravels. Thededuced maximum density of the sandy gravels has been compared with theresults of field measurements. Thus, on overcoming the difficulty in test tech-nique of large-sized materials, it will be a new method of determining theoptimum density of coarse-grained embankment materials and provides a...

本文提出了砂卵石在振动条件下的最大密度与相似级配模数之间的理想直线方程式γ_(S2max)=γ_(S1max)-tgαln(M_2/M_1),并且外推出原型大粒径砂卵石的最大密度;它与古河床大体积开挖砂卵石的密度极其吻合。从而解决了大颗粒材料试验技术的困难。为确定粗粒坝料最佳密度提供了新的方法,并为分析高土石坝的稳定提供了科学依据。
