摘要
分析了传统非饱和土三轴仪的特点及其存在问题,提出了非饱和土三轴仪的研制目标,研制出一种新型的与γ射线双源双能法同时测定土样密度和含水率技术相结合的非饱和土三轴仪。介绍了此仪器与一般非饱和土三轴仪的改进及功能实现,并用试验验证了该仪器的适用性。
Based on the analysis of characteristics and problems of the traditional triaxial apparatus,the aim for developing the apparatus is proposed. Further, a new apparatus is developed for unsaturated soil test with coincident measurements of dry density and water content of the specimen using γray measuring system. The improvements and the corresponding implement are introduced.Then, some specific tests are carried out to demonstrate the applicability of the apparatus.
