| 摘 要： | 在不同区域采集相关样品，根据不同水泥掺合比及护龄期不同，采用几种不同围压分别进行水泥土三轴压缩试验，通过试验结果得到应力一应变曲线，提出一个具有峰值后下降并趋于某定值性质的分段连续函数，并以该分段连续函数表示水泥土的力学模型。

| Abstract: | Based on the different cement blend ratio and the maintenance time in the different area,it carries through the triaxial compression test of the soil cement under the different kinds of water ponding.According to the characteristics of the stress-strain curves gained by means of the test results,it puts forward a piecewise continuous function which is possessed of the incline to certain definite values during the degression of the peak values.And the piecewise continuous function can express to the mechanic... |
