中文摘要：
非线性地基反力系数法是分析近海桩基水平大变形性状的有效途径。针对我国近海广泛分布的粉土和砂土地基，建立了无粘性土中桩基非线性地基反力系数与桩基径向土压力之间的关系，据此基于物理模型试验和现场试验结果获得了粉土和砂土地基反力系数与桩径和桩身变位之间的非线性关系，为桩基水平受力大变形分析提供了简单有效的方法，适用于不同直径桩基的计算，得到了桩基物理模型试验和现场试验结果的验证。
英文摘要：
Nonlinear coefficient of subgrade reaction method is an effective way to study the load-displacement behavior of pile foundation. For the widely distributed silt and sand seabed foundation at coastal waters of China, a maximum radial stress based analytical solution of surrounding soil resistance of pile is established. Based on the results of model test and field test, expressions of lateral coefficient of subgrade reaction associated with pile displacement and pile diameter for silt and sand are proposed respectively, which provide a simple and effective way for the large deformation analysis of monopile, and are suitable for deformation analysis of different-diameter monopile, and are proved to be reasonable by the results of the model test and the field test.
