| 1 | 结构性黄土湿陷性指标室内测定方法的探讨显示文摘对黄土湿陷性指标的室内测定,国内外都借助标准压密仪,采用单线法或双线法进行。由于多种原因,我国各部委编制的试验规程,对采用何种方法,意见尚未统一。本文首先从人工制备结构性黄土的试验成果出发,讨论了黄土的湿陷线问题,认为非饱和结构性黄土存在湿陷线,且该线与饱和结构性黄土的压密曲线重合。从而说明在此简单应力路径下,单线法和双线法是等价的。接着,从日本大阪海成粘土不同室内压密方法得出的试验结果出发,就天然结构黄土,探讨了常规标准压密试验方法的不足,提议采用等应变压密双线法,来测定结构性黄土的湿陷性指标,从而有利于实际工程应用。 | 蒋明镜 沈珠江 赵魁芝 T.Hongo 赤井俊文 陈国华 | 1999 | 水利水运科学研究1999，，1： | 15 |
| 2 | Pre-Failure Behavior of Deep-Situated Osaka Clay显示文摘Great interest has been aroused on deeply-situated Osaka clay since Kobe Earthquake in1994.In this paper is presented the analysis on the results of a series of lab tests on Osaka clay situatedfrom 100m to 1500m under the ground.The wave velocity method,bender element method,LDT and theformula derived by the authors are used,focus is put on the pre-failure mechanical behavior of the clay.The analysis shows that,(i)pore-pressure coefficient B is less than 1.0,(ii)the relationship between shearmodulus and Poisson's ratio is not in agreement with that reported before,(iii)the modulus measured withLDT is still less than that measured with bender element method,and(iv)there are two threshold strains,within which the clay can be considered as elastic,and both of them are larger than that reported before. | T.HONGO M.FUKUDA T.ADACHI F.OKA | 1998 | China Ocean Engineering1998，13，4： | 5 |
