DEVELOPMENT OF SERVO-CONTROL ROCK AND SOIL AGGREGATE PERMEABILITY TEST APPARATUS
摘要
Abstract
The permeability of rock and soil aggregates ( RSA) is important for engineering construction, prevention and treatment of landslides in RSA. This paper gives a summary of the previous studies of the rockfill permeability test apparatus. The Tsinghua University test system is special for its recycle of water. The Hohai University test instrument is horizontal. Its lifter has the accurate control of the water level for its higher and lower water supply. Nanjing Hydraulic Research Institute studied the influence of water board, sample preparation methods and an-ti-seepage of the wall to the permeability test. The Luo Yuzai permeability test apparatus is special at its capability for providing the continuous high-pressure water without air. Using self-made permeability test instrument, Zhou Zhong and others from Central South University studied the permeability coefficient and its influencing factors of RSA. On the basis of previous studies, we have developed a servo-control rock and soil aggregate permeability test apparatus. The apparatus can servo-control the velocity and stress of the water supply, provide high-pressure ( < 2MPa) and adjust the velocity of the seepage. It is convenient to operate. The apparatus can study the permeability of the RSA successfully.关键词
