| 摘 要： | 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。

| Abstract: | Aiming at over dense pile foundations of phase- i project of gas-turbine pedestals that brings diffi- culties to construction work, the paper makes dynamic analysis on pedestals by ANSYS modeling. It is discov- ered that it has less impact on dynamic response of upper structure of pedestal to adjust quantity of pile foun- dations 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. |
