学校变革进程中教师专业发展现状的调查研究

根据对湖北省10所学校教师专业发展现状的调查研究,发现身处于学校变革进程中的中小学教师在专业发展上存在一些问题:教师培训缺乏针对性和操作性,学校领导对教师成长的关心和重视不够,教师专业发展亟需高层次的专业引领,教师工作压力大、专业发展状态堪忧,等等。据此提出相关建议:改进教师培养方式,让教师培训更具实效性;改善教师生存状态,让教师职业更具幸福感;帮扶薄弱学校教师,让教师成长更具质感;营造良好的学习与研究氛围,让教师校园生活更具美感。     

分光光度法测定土壤中亚硝酸根离子

采用显色分光光度法测定了土壤中亚硝酸根离子的含量。在酸性条件,土壤中的亚硝酸根离子与对氨基苯磺酸发生重氮化反应生成重氮盐,在碱性条件下,重氮盐与α-萘胺发生偶联反应而显色。该文系统考察了偶氮化反应和显色反应条件及土壤样品预处理对测定的影响。在显色反应中用氢氧化钠代替醋酸钠调节pH值可减少缓冲溶液用量,加快显色速度。在优化测定条件下,521 nm波长处的吸光度与亚硝酸根离子含量成线性关系,线性范围为0.0050-0.1000μg·mL^-1,线性相关系系数为0.9998;平均加标回收率为99.58%,相对标准偏差为1.89%。结果表明用于实际土壤样品测定时,改进后的方法更简便和快速,灵敏度和精密度有较大提高。

Bearing capacity and load transfer mechanism of a static drill rooted nodular pile in soft soil areas

The static drill rooted nodular pile is a new type of pile foundation consisting of precast nodular pile and the surrounding cemented soil. This composite pile has a relatively high bearing capacity and the mud pollution will be largely reduced during the construction process by using this type of pile. In order to investigate the bearing capacity and load transfer mechanism of this pile, a group of experiments were conducted to provide a comparison between this new pile and the bored pile. The axial force ofa precast nodular pile was also measured by the strain gauges installed on the pile to analyze the distribution of the axial force of the nodular pile and the skin friction supported by the surrounding soil, then 3D models were built by using the ABAQUS finite element program to investigate the load transfer mechanism of this composite pile in detail. By combining the results of field tests and the finite element method, the outcome showed that the bearing capacity of a static drill rooted nodular pile is higher than the bored pile, and that this composite pile will form a double stress dispersion system which will not only confirm the strength of the pile, but also make the skin friction to be fully mobilized. The settlement of this composite pile is mainly controlled by the precast nodular pile; meanwhile, the nodular pile and the surrounding cemented soil can be considered as deformation compatibility during the loading process. The nodes on the nodular pile play an important role during the load transfer process, the shear strength of the interface between the cemented soil and the soil of the static drill rooted pile is larger than that of the bored pile.     

Vertical vibration of a large diameter pile embedded in inhomogeneous soil based on the Rayleigh-Love rod theory

The vertical vibration of a large diameter pile embedded in inhomogeneous soil with hysteretic type damping is investigated based on the 3D axisymmetric model. Firstly, the pile is assumed to be a Rayleigh-Love rod with the consideration of its transverse inertia effect. Following this assumption, the pile-soil system is divided into several segments according to the stratification of the surrounding soil, and the dynamic interactions of the adjacent soil layers are simulated using the distributed Voigt model. Meanwhile, the surrounding soil is discretized into finite annular vertical zones to consider its radial inhomogeneity, and the force equilibrium and displacement coordination are satisfied at the interfaces of the adjacent soil zones and the interface of the pile-soil. Then, the analytical solution in the frequency domain and the semi-analytical solution in the time domain are obtained by solving the vibration governing equations of pile-soil system. Based on the solutions, a parametric analysis is conducted to investigate the influence of the transverse inertia effect on the dynamic response of the large diameter pile and its relationship with the pile parameters and the radial inhomogeneity of the surrounding soil. Finally, a comparison with the measured result and two other calculated results is presented to verify the effectiveness of the present solution.
