The Mo powder and Nb powder was used as raw material, the Mo-10Nb alloy target was prepared by different sintering condition (non-pressure sintering and hot pressing sintering). The density, phase composition, microstructure and elemental distribution of Mo-10Nb alloy targets were determined by X-ray diffraction and scanning electron microscopy. The results showed that prepared by hot pressing Mo-10Nb alloy target density of 9.618 g/cm3, grain size 20 ~ 30μm, Mo and Nb element distribution.

The stability of the concrete shear wall is composed of the overall stability and wall limb local stability, the overall stability and local stability calculation formula can be used the same form of expression. Based on the theory of stability calculation of elastic thin plate, the trilateral bearing and quadrilateral bearing wall limb length factor is derived. And then, it pointes out the disadvantages of the current code and design software, and gives the corresponding solution.

Shaft tower has the characteristics of long service time and once the damage will affect the normal production, thus ensuring the normal use is particularly important. Vibration made by the Multi rope friction hoist operation will lead to floor resonance, thus" card tank" and" rolls over" loads determining the hoist layer structure arrangement become very critical. Through the analysis of existing data, the shaft tower vibration characteristics and seismic behavior research is analysed and forecasted.

The complex tower structure appears as modeling of palms together, which is designed as steel frame-core tube structure. This paper uses SAP2000 to analysis seismic response respectively on the linear and elastic-plastic stage, and puts forward some specific suggestions for seismic design according to the analysis and calculation.

The conventional triaxial compression(CTC), triaxial compression(TC) and reduce triaxial compression(RTC) of ordinary loess in Xi，an Ba He was conducted with GDS stress path tests and the strength behavior and deformation capacity of loess was studied. The experimental results showed that the larger the initial moisture content, the smaller the shear strength. The strength characteristic of loess varied under different stress path. Relationships between σ and ε was strain hardening model. The peak strength of CTC is larger than that of TC and the peak strength of RTC was smaller.
