土样结构受到扰动,必然导致应力应变关系的改变和强度的降低,这一事实已经引起人们的关注。结构扰动的影响,在各种强度试验中均可发现,但以单向固结试验的e～logP曲线表现得最为明显,即曲线有明显的改变。这种改变具有规律性,而且可用数理方法加以定量评价。一、e～logP曲线的客观规律土在形成的漫长岁月中,由于受到地质的、物理的、或化学的种种因素的影响,而达到某种程度的固结,形成一定的结构强
The fact that the soil-like structure is disturbed will inevitably lead to the change of the stress-strain relationship and the reduction of the strength. This fact has drawn people’s attention. The influence of structural disturbances can be found in various strength tests, but the e-logP curve of the one-way consolidation test is the most obvious, that is, the curve has obvious changes. This change has regularity and can be quantitatively evaluated using mathematical methods. I. The objective laws of the e~logP curve In the long years of formation, due to various geological, physical, or chemical factors, they reach a certain degree of consolidation and form a strong structure.
