摘要
为了分析水泥土搅拌桩处理软土路基的工程适宜性,依据水泥土配合比设计相关规程进行了水泥土配合比设计,通过对大量水泥土试件进行室内抗压强度和抗剪强度的力学参数试验,分析了水泥掺入比、养护龄期这2个因素对水泥土无侧限抗压强度、抗剪强度参数的影响,并借助乘幂回归模型进行数学统计分析,得到了具有强相关关系的函数方程,这为后期设计方案的制定和实施提供了数据支持,具有一定的实践价值和理论意义。
In order to analyze the engineering suitability of cement - soil mixing pile to deal with soft soil road.- bed, Mix ratio tests of the soil cement were executed based on the relevant regulations of mix design. By labo- ratory test of compressive strength test and shear strength test to the specimens, the mechanical parameters of compression strength and shear strength were obtained. Then according to the laboratory test results, the effects of cement mix- ratio and curing age on unconfined compression strength indexes and shear strength parameters were analyzed. At last, based on power exponentiation regression model for mathematical and sta- tistical analysis, functional equations with strong correlation of cement - soil intensity and shear strength pa- rameters with cement mix - ratio and curing age were determined which would be useful to provide data sup- port for the design of construction scheme and be of some practical value and flleoretical significance.
