不同受载方式下桩侧阻的渗水力模型试验研究

利用ｎ·ｇ渗水力土工模型试验对垂直受载桩在桩顶压桩，桩顶拔桩及桩底托桩等受载方式下的桩侧摩阻力的发展规律进行了试验研究，得到了侧阻与位移的关系、侧阻强度沿桩身的分布以及侧阻强度和相应截面位移之间的关系，试验成果在一定程度上揭示了侧阻发展的机理。

Study about the shaft resistances of piles in different loading ways by hydraulic gradient test

In this paper, a series of n·g hydraulic gradient tests have been done to study the shaft resistances of vertically loaded piles in different loading ways. The loading ways include: compressive loading on pile top, tensile loading on pile top and tensile loading on pile bottom. The experimental results include the relationship between shaft resistance and settlement, the distribution of shaft resistance intensity along pile and the relationship between shaft resistance intensity and displacement. The experimental results have, to a certain extent, revealed the mechanism of shaft resistance.
