摘　　要：螺杆桩作为一种新型桩,其独特的变截面设计使其承载机理和工作性状要比传统的直线型桩复杂的多,通过静载试验研究螺杆桩的工作性能,确定其荷载传递机理、受力模式,使螺杆桩更好的应用于我国基础设施的建设中,具有十分重要的理论意义和工程实际意义。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 resuits. Researching its work performance, load transfer mechanism, the force mode, has important theoretical and practical significance.
