摘要
借鉴测定土壤水分特征曲线的方法,根据风化砂的特点,对测定原状全风化砂水分特征曲线的试验装置、测量仪器、取样、试验方法及数据拟合进行了研究。提出了采用TDR一张力计法测定原状全风化砂H(θ)曲线的方法。
Making use of the method of determining the water content characteristics curve of soil and arcording to the characteristics of weathered sand, the testing setup,measuring devices,sampling, method of testing and data for the water content characterstics of undisturbed com-pletely weathered sand are investigated. Adoptation of the method of TDR-tensometer to cali-brate undisturbed weathered sand H(8) curve is proposed
