在土工试验中,如何克服仪器中的传力机构以及土样与容器(切土环刀)间的摩阻力问题是仪器设计中急待改进的一个重要问题。土木工程学会1980年12月在南京召开的有关土工仪器系列型谱会议曾建议研究压缩试验的侧壁摩阻问题。在现行水利电力部土工试验规程中,把侧壁低摩阻试验作为固结仪的一项改进列入附录。
In the geotechnical experiment, how to overcome the frictional resistance between the force-transmitting mechanism in the instrument and the soil sample and the container (cutting ring knife) is an important problem in the design of the instrument that needs urgent improvement. The Civil Engineering Society’s series of geotechnical spectrum meetings held in Nanjing in December 1980 suggested that the side wall friction resistance of compression tests be studied. In the current Ministry of Water Resources and Electric Power Ministry of soil test procedures, the sidewall low friction test is included in the appendix as an improvement of the consolidation instrument.
