小浪底大坝心墙中高孔隙水压力的研究

土石坝的施工会在大坝心墙和地基中产生超静孔隙水压力。对于高土石坝，施工期心墙防渗体内产生的超静孔隙水压力难以有效消散，因此坝体内部可能会出现较高的孔隙水压力，这对大坝的稳定性和安全性将产生重要影响。黄河小浪底大坝坝高154m，是目前国内已建最高的心墙土石坝。本文利用基于Biot理论和剑桥模型的有限元固结程序对该大坝进行了二维平面应变固结分析，计算施工期及坝体竣工后心墙内的孔隙水压力。计算发现，坝体竣工时心墙中将出现较高的孔隙水压力，最大值为1250kPa，是上覆盖土重的62．5％，长期的观测资料也发现心墙内的孔隙水压力比较高。对比实测数据和有限元计算结果，发现小浪底心墙中出现最大的孔隙水压力可达1400kPa，而且实测消散速度要远小于有限元预测结果。这一结果充分说明高土石坝中可能产生较高的孔隙水压力，对此应予以足够的重视。

Quantification of the layer dispersion degree in polymer layered silicate nanocomposites by transmission electron microscopy

As the performance of polymer layered silicate nanocomposites strongly depends on their interior layer dispersion, quantification of the layer dispersion degree is needed. In this work, a new methodology was developed to determine the dispersion parameter D_0.1, based on the measurement of the free-path spacing distance between the single clay sheets from the transmission electron microscopy (TEM) images. Several examples of exfoliated, intercalated, and immiscible composites were studied. It was found that the exfoliated composites had D_0.1 over 8%, while that of intercalated composites were between 4 and 8%. In the case of intercalation, a high frequency peak appeared at a short spacing distance in the histogram, which was a characteristic of the intercalation, distinct from the exfoliation. The main utility of this TEM methodology is for the quantification of exfoliated or intercalated samples with small number of layers with stacks. The dispersion parameter D_0.1 below 4% was suggested to classify as immiscible. A unique advantage of the TEM measurement is that the dispersion degree of different fillers can be counted individually.

Synthesis, characterization and catalytic application for wet oxidation of phenol of iron-containing clays

High-surface-area pillared clays (PILC) were prepared from naturally occurring montmorillonites by exchanging interlayer ions to polyoxocations containing (i) aluminum (Al₁₃-PILC), (ii) iron adsorpted onto Al₁₃-PILC, and (iii) iron and aluminum located within the same complex (Fe_0.8Al_12.2-PILC). The obtained Fe_0.8Al_12.2-PILCs were characterized by DR–UV–vis and IR spectroscopy, XRD, ESR, scanning electron microscopy and low temperature N₂ adsorption measurements. Important factors affecting catalyst activity and phenol removal efficiencies have been studied, i.e. the effect of pH, temperature, catalyst concentration and stability of the catalyst.
