摘要(Abstract):

某电厂燃机基座一期工程桩基过密造成施工困难,通过有限元ANSYS程序建模对基座进行动力分析,发现调整底板桩基数量对基座上部结构的动力响应影响不大,因此可在满足沉降和强度前提下,通过减少桩基数量来方便施工和降低造价。
Aiming at over dense pile foundations of phase-ⅰproject of gas-turbine pedestals that brings difficulties to construction work,the paper makes dynamic analysis on pedestals by ANSYS modeling.It is discovered that it has less impact on dynamic response of upper structure of pedestal to adjust quantity of pile foundations at the base board.Therefore,the pile foundations can be reduced on the premise that settlement and strength can be ensured to facilitate construction work and reduce the cost.
