考虑到淤泥质软土易扰动 ,且存在流塑性 ,需要采用较多数量的原状土样 ,进行重复的土性试验 ,以得到平均值来确定土性参数 ,这将增加工程费用。运用数理统计方法中的回归分析方法通过较易取得的物理指标反演较难得到的力学性质指标 ,并通过实例评价回归分析的实用性。从而得出回归分析方法在初步设计阶段的实用性 ,同时 ,回归分析方法还可以作为检验室内试验指标的参考依据。 Taking into account the muddy soft soil disturbance, and the existence of fluidity, the need to use a larger number of undisturbed soil samples, repeated soil tests to get the average to determine the soil parameters, which will increase the cost of the project. By using the method of regression analysis in mathematical statistics method, the more difficult to obtain mechanical properties indexes are retrieved through the more easily obtained physical indexes, and the practicality of regression analysis is evaluated by examples. The conclusion is that the regression analysis method can be used as a reference to test laboratory test indicators at the same time.
