我国黄土工程性质研究的发展

本文首先分三个历史阶段简要回顾了我国黄土工程性质研究的发展历程。然后对近年来我国学者在黄土动力特性、非饱和土力学特性的理论与测试技术、湿陷性黄土增湿与减湿特性及结构强度特性、厚层Ｑ＿２黄土的湿陷特性及评价，湿陷性黄土中的桩基试验与评价以及湿陷性黄土地基处理新技术等方面的研究成果进行了评述，最后指出了黄土工程性质领域目前需要进一步研究的几个问题。

Development of Loess Engineering Properties Research in China

This paper firstly gives a brief account of the therr historical periods of the development of loessengineering properties research in China;Secondly reviews the achievements made by Chinese scholars in recentyears in loess dynamic behaviors,the theory and test of unsaturated soil mechanics characters , moistening ordemoistening properties and structural strength characters of collapsible loess,collapsibility of thick Q_2 loess and itsevaluation,test and evaluation of pile foundation in collapside loess,the new technique of collapsible loess qroundtreatment and so on;and finally points out some problems which remain to be further studied in loess engineeringpropertles.
