[提要]  改變過(guò)去動(dòng)力機(jī)械基礎(chǔ)在水平旋轉(zhuǎn)振動(dòng)作用下，不考慮土的慣性作用的作法，將待求參量由3個(gè)變?yōu)?個(gè)（稱為動(dòng)力分析中的四參數(shù)模型）。應(yīng)用這個(gè)新模型進(jìn)行分析，可獲得更符合實(shí)際的計(jì)算結(jié)果。
[關(guān)鍵詞]  水平、旋轉(zhuǎn)耦合振動(dòng) 參振土質(zhì)量 動(dòng)剛度

Unlike before, the authors have proved that the inertia effect of base soil must be considered and the in. ertia action of soils is very evident by a number of tests. And then, the number of the parameter to be deternuned shall change from 3 t0 4.Here, the model is refered to as 4 parameter model. Only using the new model, the results of dynamic computation could be conformable to practice well.
Keywords: couple vibration; sliding; rotation, participating soil mass in vibration; dynamic rigidity
