摘要
对西安理工大学研制的新型旋转触探仪进行调试并进行了5个干密度,4个含水率试样的室内旋转触探试验。通过对实验数据的分析定性得出了:相同含水率条件下稳定锥尖阻力与稳定扭矩随干密度增大而增大;相同干密度条件下稳定锥尖阻力与稳定扭矩随含水率增大而减小。试验结果也为通过旋转触探定量确定岩土物理力学性质参数提供了依据。
A new rotary penetration apparatu,which was developed by Xi＇an University of Technology,is verified,and the tests on Xi＇an loess samples with five different dry densities and four water contents are done using the apparatu.The test results show that the probe resistance and torque increase with dry density increasing in same water content condition at a certain depth of 5 m,meanwhile the probe resistance and torque drop with increasing of water content in same dry density condition.The test result will provide good basis for determinating the soil physical and mechanical properties through the rotary penetration test.
