通过土工离心模型试验,施加95g离心加速度,研究桩基在不同水平加载高度下,加载高度对桩基水平承载力、位移、弯矩、桩身倾斜程度等的影响,通过对水平加载高度h=159 mm,h=135 mm两组离心模型试验数据的对比分析,发现在相同位移条件下桩基水平承载力随加载高度的增加而减小;在相同荷载条件下桩基弯矩、倾斜程度、位移随加载高度的增加而增加。
Through the centrifugal model test of geotechnical engineering, the centrifugal acceleration of 95g was applied to study the influence of loading height on the horizontal bearing capacity, displacement, bending moment and pile inclination of piles under different levels of loading height. The horizontal loading height h = 159 mm and h = 135 mm respectively, it is found that the horizontal bearing capacity of the pile decreases with the increase of the loading height under the same displacement. Under the same load, the bending moment, The displacement increases as the loading height increases.
