摘要
海积软土是一种结构性土 ,具有结构连结强度。其压缩曲线呈现出超固结土的压缩曲线形式。强度曲线为二段折线 ,在应力小于σ′k 时表现出超固结土的力学特性。而当应力水平高于这一临界值时 ,表现出正常固结土的力学特性。对其结构连结的成因进行了简单探讨。
Marine soft soil is a kind of structured soil with strength of structural connection. Its compression curve is similar to that of over consolidated soil. The strength curve of shear two section dog leg path shows mechanical property of over consolidated soil if the stress is lower than σ′ k . Mean while, if the stress level is higher than the critical value, marine soft soil shows mechanical property of normally consolidated soil. The cause of formation of connection strength was discussed in this paper.
