Half-screwed pile is a new kind of pile. Because of the unique design of variable cross-section, bearing principle and working traits are much more complex than the traditional linear pile. The vertical load transmission mechanism thoroughly is analyzed about half-screwed pile based on the static load experiment results. Researching its work performance, load transfer mechanism, the force mode, has important theoretical and practical significance.

GFRP bars and PC strand combination pile that is configuration GFRP bars in the compression zone of the general pile, in the tension zone configuration PC strand. Pile construction is completed and before the excavation, applied partially prestressed for the tension zone of PC strand, so that GFRP bars in tension, with the excavation pit, GFRP bars tendons pulling force gradually reduced; When the excavation to a certain depth, the second prestressed steel strand so until the excavation is completed. In summary, the technology features is GFRP bars, concrete piles, PC strand all in tension. This makes full use of the concrete compression performance, GFRP bars and PC strand tensile good performance characteristics.

GFRP bars pile as supporting structures for application in foundation engineering, the construction process of molding and banding quality directly affects the safety of the structure, ease of construction and appearance quality. Through practice on multiple projects, worked out a more mature construction process, better control of the quality of construction projects GFRP bars, standardized operating procedures.

In the context of "New Engineering", this paper has made some explorations on the construction of software engineering courses. The background of course construction is analyzed to identify the weak links in course construction. The top-level plan of "four in one and three in combinations" has been formulated to provide a unified framework for construction. It elaborates on the course content to keep up with technological development, combine online teaching with optimized teaching methods, cooperate with schools and enterprises to educate students, and promote learning through competition. Practical results show that students gradually acquire the basic theory, design development technology, and application innovation capabilities of software engineering, and realize the zero-distance docking between academic and employment.
