摘要： 螺杆桩作为一种新桩型研究较少，根据泥岩地基的螺杆桩静载荷试验资料，分析了螺杆桩竖向荷载的传递机理，给出了极限承载力的计算公式，为今后泥岩地基的螺杆桩应用提供依据。

Abstract: As a new type pile, Research on Halfscrewed Filing Pile is far from enough. The vertical load transmission mechanism thoroughly is analyzed about Halfscrewed Filing Pile in mudstone foundation based on the static load experiment results, except ,ultimate bearing capacity formula is deduced and the reliability basis of the halfscrewed pile design is provided.

Key words: Halfscrewed Filing Pile, mudstone foundation, bearing capability, expressions of the ultimate bearing capability
