该种模型考虑了由于风速的不稳定所带来的作用在风力机叶片上分布载荷的不确定因素，并假定风力机的设计寿命为20年。
This model accounts for the uncertainty about the loads acting on the wind-turbine rotor blade by the unstable wind distribution. A 20-year design lifetime is considered.
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.
脱层区域假定为椭圆形状，本文研究了在双轴载荷作用下对称正交铺设层板脱层屈曲的临界载荷，脱层厚度、半轴比、子层角以及载荷比对临界载荷的影响均进行了研究。
The delamination is assumed to be elliptical in shape. In this paper the critical load of delamination buckling for a symmetric cross-ply laminate acted on by biaxial load is investigated.
