潮位变化是影响群桩基础承载性能的一个重要因素。针对潮汐河段群桩基础的承载性能，根据相似性原则，对某大桥南侧主桥群桩地基基础开展考虑潮位影响的室内模型试验，研究了潮位变化引起的低频循环荷载对群桩基础承载性能的影响，试验结果表明：周期性的潮位涨跌使地基土产生硬化，增大了群桩基础的工后沉降。

Tide change is an important factor which affects bearing behavior of pile - group foundation. According to the bearing behavior of the pile - group foundation in strong tidal river, and by the similarity principle, indoor model tests for pile - group foundation of a southern main bridge were done. In those tests, the tidal influence was considered. Then the author did research in low - frequency cyclic loading which caused by the change of tidal level effect on settlement and bearing capacity. The research result indicates that the cyclical variation of tidal level lead to the hardening of foundation soil. It causes the post - construction settlement increasing of pile - group foundations.
