摘要:
为获得无固定连接式压缩机基础的动力特性，试验以某天然气集气站实际工程为依托，采用现场地基基础压力监测、原位动力测试相结合的方法对该类型压缩机基础进行了研究.研究结果表明：(1) 无固定连接式压缩机基础底部的压力受压缩机动力作用的影响较小且其影响随深度的增加而减小；(2) 各土层压力波动随时间推移约20 d后趋于稳定，稳定后的压力与静压力差值较小；(3) 基础设计采用的碎石垫层吸收了大量振动能量，具有明显的减振效果，削弱了动力作用对地基基础的影响；(4) 基槽侧边的碎石垫层在限制机组位移的同时降低了振动对基础的影响.
Abstract:
In order to obtain dynamic properties of non-fixed compressor foundation, the field monitoring and in-situ dynamic test were used to study the compressor foundation according to actual gas gathering station project. The results show that: (1) The bottom pressure of the non-fixed compressor foundation is less affected by the dynamic action of the compressor；(2) Its influence decreases with the increase of the depth.20 days later the soil pressure tends to be stable, and the difference between the steady pressure and the static pressure is small; (3) The gravel cushion adopted in the foundation design absorbs a great deal of vibration energy, which has obvious damping effect and could weak the influence of the dynamic action on the foundation; (4) The side of the gravel cushion can reduce the influence of vibration on the basis and limit the displacement of compressor.
