黏性土渗透性温度效应实验研究 总被引:5,自引:0,他引:5
由于全球气候变暖、城市热岛效应加剧和核废料地质处置等原因,温度对黏性土工程性质的影响日益受到关注。本文在实验的基础上,采用直接测量法,对南京下蜀土、淤泥质土以及混合土3种试样,进行了5°~45°温度下的变水头渗透实验,分析了温度对黏性土渗透性的影响。实验结果表明:温度对3种试样的渗透性均有较大影响。温度越高,渗透性越大; 试样的密度越大,渗透系数随温度变化率越低; 在3种试样中,混合土的渗透系数高于淤泥质土和下蜀土的对应值,而淤泥质土的渗透系数又略大于下蜀土。最后对黏性土渗透性的温度效应机理进行了分析,认为水的动力黏滞性,黏粒的双电层厚度以及土的微结构三方面因素的共同作用引起了黏性土渗透性的温度效应。

A heavy haze episode caused by agricultural burning occurred in Nanjing from November 7 to November 8, 2009. PM10 samples were collected on normal and hazy days from November 1 to November 14, 2009 at both city and suburban sites of Nanjing. Sixteen PAHs were measured during the day and at night. The results show that the concentrations of the particles were as high as 579.55 and 573.43 μg/m3 during the haze episode at the city and suburban sites, respectively, 3–4 times higher than those on a normal day. The proportions of fine particles during the haze episode were also higher than those on a normal day. The changes in the concentrations of PAHs were in accordance with the concentrations of the particles. High-molecular-weight PAHs composed approximately 80% of the total PAHs on normal days and during the haze episode. The concentration of PAHs in fine fractions significantly increased during the haze episode, and this increase was most obvious at night at the city site. The proportion of total carcinogenic PAHs in fine particles was relatively high during the haze episode at both sampling sites, particularly at night at the city site. 相似文献

Correlation dimension of paddy soil strength in China 总被引:2,自引:0,他引:2
Embedding phase space Rm is reconstructed from the spatial series g(x) of cone indices measured in two paddy fields near Nanjing, China. The correlation dimension D2m for each field is derived from the correlation integral Cm(r) and the neighbours distance r in log–log scale. Results show D2m increases as m, and tends to 5.0, which expresses the estimate of correlation dimension for each soil strength profile measured. 相似文献

The linear relation between the particle concentration and the output voltage of a light extinctiometer used to measure particle concentrations has been derived and calibrated. A time integration method was introduced to determine the characteristic parameter of such a measuring system. This characteristic parameter which is proportional to the extinction coefficient is found to be in good agreement with its theoretical value. As an example, in a vertical tube the increasing particle concentration was measured behind a developing flat interface between a gas and a gas-particle mixture as a function of time.On leave from East China Institute of Technology, Nanjing 210014, The People's Republic of China 相似文献
