摘要
综合笔者建立的应变速率-应力关系和应变速率-时间关系,得到湿软土壤压力-下陷-时间方程,进行了一系列室内土槽压板沉陷蠕变试验,结果表明,方程良好地似合实测数据且与Burgers方程相比具有如下几方面的优越性:(1)由某两种压力下的试验结果可以较精确地预测其它压力下的压陷行为;(2)方程系数易由试验结果确定;(3)方程形式简单。
As the application of fundamental research of rheological peoperties of soils, a simple and meanful pressure-sinkage-time equation is established. A series of creep tests of circle plate in a soil bin is done. And the result indicates that the prediction of the equation is consistent with measured data, and it is more advantageous than the rheological equation of Burgers model in following aspects: ( 1 ) From experimental results at two certain pressures, sinkage behavior at other pressures can be predicted more accurately; ( 2 ) Equation parameters are easy to determine from test results; ( 3 ) The form of equation is simple.
