摘要
P&H无张力灌注桩基础是一种新型的风机基础,已用于我国多个风电场中.本文基于陕西某风电场P&H无张力灌注桩基础的设计资料,利用FLAC3D有限差分软件建立土体和基础的模型.分析了锚杆和基础在极端荷载作用下的受力和变形特性,讨论了锚杆这一结构构件在P&H无张力灌注基础中的作用,以及不同锚杆预应力对基础内部应力分布及变形的影响.
Patrick ＆ Henderson （P＆H） tensionless pile wind turbine foundation is a new type of fan foun- dation, which has been applied in lots of wind farms in our country. Based on the design information of a wind farm in Shanxi province, a simulation of P＆H tensionless pile wind turbine foundation and surrounding soil was achieved with FLAC3 D. This paper analyzed the stress and deformation properties of anchor and foundation. The function of the anchor in P＆H tensionless pile wind turbine foundation was discussed as well as the effects of pre -stress on the stress distribution and deformation in the foundation.
