合肥地区螺旋板载荷试验方法的研究

Research on the approach to screw plate load test in Hefei area

螺旋板载荷试验因能测试深层地基土的承载力而被广泛应用。文章通过总结螺旋板载荷试验与平板载荷试验的对比试验结果,以及螺旋板载荷试验速率对合肥地区地基承载力的影响,进而探索研究螺旋板载荷试验方法的标准以及其在合肥地区的适用性;提出了螺旋板载荷试验确定合肥地区地基承载力的建议方法。该方法的建立为今后合肥地区工程设计与施工建设提供了有益的参考依据。

Screw plate load test has been widely used to test the bearing capacity of deep foundation soil. Through the conclusive comparison of screw plate load test and plate load test, and in view of the effect of screw plate load test rate on the bearing capacity of Hefei＇s foundation, the test methodology standards of screw plate load and its applicability in Hefei area are studied. The suggestion of using screw plate load test to determine the bearing capacity of foundation in Hefei area is put forward, which provides a useful reference for the future engineering design and construction in this region.
