Natural frequency of tapered high pier considering pile-soil interaction

In seismic design of tapered high pier, the analysis of natural vibration frequency is of great importance. According to the engineering features of tapered high pier in mountainous area, a vibration calculation model was set up considering the tapered pier characteristics and pile-soil interaction. Based on Southwell frequency composition theory, it consists of elastic deformation of bridge pier and the rigid deformation of group piles, which are respectively solved by the finite-element method and energy method, and then the natural frequency is derived. The comparison between the measured and calculated results shows that the calculation errors with and without considering pile-soil interaction are 4.9% and 14.7%, respectively. Additionally, the main parameters (pier height, section variation coefficient and lateral foundation horizontal proportional coefficient) affecting natural frequency were investigated. The result shows that natural frequency ascends with the increase of the lateral foundation horizontal proportional coefficient; and it is quite necessary to consider the pile-soil interaction in natural frequency calculation of tapered high pier.     

定向钻穿越施工控制方法

定向钻穿越在管道与隧道工程中运用越来越广泛,但施工中若控制不当,对地表及其上建（构）筑物会带来如冒浆、建（构）筑物开裂等不利影响,为更好地进行施工设计,减弱负面影响,本文结合湖北省境内忠县-武汉输气管线定向钻穿越监利洪湖大堤的工程实例,建立相关地质、工程模型,分析了定向钻穿越施工对上覆土体变形破坏的成因,由此提出了定向钻施工控制方法．     

Vibration compaction characteristics of rock filling embankment

The dynamic model experiment of the rock filling embankment was carried out to investigate the vibration compaction mechanism. The rock filling materials were compacted by the plate-vibrated compactor, and the characteristics of the rock filling materials, such as settlement, pressure change and response waveform, were measured by the dynamic earth pressure gauge and accelerometer. Moreover, a new method for detecting the compactness of the rock filling embankment was proposed based on the maximum dry density and modulus of deformation. The results show that the process of vibration compaction includes compact, elastic deformation and loose stages, and the vibratory pressure transfers to the surroundings from the vibration center in non-linear rule. Furthermore, the test results obtained by the present method are basically in agreement with those obtained by the traditional method, and the maximum relative error between them is about 0.5%.

一种基于三维模型投影的人脸识别新方法

研究了使用三维人脸模型进行不同姿势下的人脸识别问题,提出了一种三维建模二维识别的人脸识别算法,首先使用该方法将三维模型向不同方向投影,进而将不同姿势的二维图像与不同方向的投影结果相匹配,进行人脸识别。研究了使用Minolta Vivid 910进行数据获取,创建三维模型的方法和过程。实验结果表明,在进行不同姿势的人脸识别时,该方法的识别速度快于三维可变形模型方法,识别率远优于使用二维正面图像作为模板的人脸识别方法。
