摘要
非饱和土的吸力测试是非饱和土研究中最重要也是最基本的测试技术。回顾了非饱和土现场试验的历史,结合近年开展的膨胀土渠道现场观测实践,从观测设备的原理出发,介绍了现场观测仪器及其埋设方法、观测试验成果,其经验可供岩土工程师在非饱和土现场实践中参考。
In this paper, the observation and measure technology of matrix suction of unsaturated soils on-site is reviewed. From the principium of equipment, some apparatuses and techniques used in lab or field test is introduced, it is helpful experience for studying at unsaturated soils for geo-engineers.
