粘性土中侧向受载桩的模型试验研究

本文简单介绍了模型桩制作和粘性土固结的方法,通过初始静载试验、循环荷载试验和循环荷载后再加载试验,分别探讨了荷载大小、频率、循环次数和荷载历史等因素的影响,并根据试验结果作出了沿桩身不同深度的p-y曲线,最后探讨了粘性土侧向基床系数模式和影响因素。

Study on the Model Test of Lateraliy Loaded Piles in Cohesive Soils

In this paper, the methods for making model piles and for consolidation of cohesive soils are introduced. By the model test of short-term static loading, cyclic loading and reloading after cycling, the influences of the magnitude, frequency, number of cycles and history of load on the behavior of pile are analyzed.Based on the data of the model test, p-y curves in different depths of pile are determined. Finally, the mode and influencing factors of lateral subgrade coefficient of cohesive soils are analyzed.
