泥岩地基螺杆桩竖向承载性能试验分析

Test Analysis on the Bearing Behavior of Half-screwed Filing Pile in mudstone foundation

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。

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