大量试桩资料表明，桩身荷载传递函数曲线多符合双曲线模型，故有必要对基桩荷载传递性状进行非线性分析。
Many static test data indicate that, the load-transfer curves can be well fitted with hyperbola, so nonlinear analysis on behavior of load transferring along pile shaft is necessary.
非双曲线型非线性系统同宿切面点和同宿横截点的存在，使得其时间序列的去噪或轨迹重影变得十分困难。
The presence of homoclinic tangencies and homoclinic intersection makes it difficult if not impossible, to denoise or shadow the trajectory of a non-hyperbolic nonlinear system.
筏板下的群桩假定为相互作用的非线性弹簧，使用双曲线函数拟合载荷试验的Q-S曲线，并用它来模拟桩在荷载下的非线性响应。
The single pile load test's Q-S curves can be matched by the hyperbola function. The non-linear characteristic of the piles can be modeled by the hyperbola function.
