黄土的建筑特性的研究,对于我国建设事业的发展有着重要的意义。我们先后对甘肃、陕西两地的黄土,分别进行了八组不同湿度的压缩试验,它的物理化学性质如表1、2、3。 所有压缩试验都按一般“双线法”进行,操作步骤按水利部土工试验操作规程进行,每组试件的原始湿度均经人工制达要求的湿度(其中一个达饱和),关于压缩系数δ_ρ与湿陷系数δ_ωρ的计算按下式进行: The study of the loess’s architectural characteristics is of great significance to the development of China’s construction industry. We conducted eight groups of different humidity compression tests on loess in Gansu and Shaanxi respectively. Its physical and chemical properties are shown in Tables 1, 2, and 3. All compression tests were performed according to the general “two-wire method”. The operation steps were carried out according to the Ministry of Water Resources Geotechnical Test Operating Procedures. The original humidity of each set of specimens was artificially produced to the required humidity (one of which was saturated), and the compression coefficient δ_ρ. Calculate the collapsibility coefficient δ_ωρ as follows:
