摘要

通过三轴蠕变试验和平面应变蠕变试验，研究路堤下深厚的海相沉积软土侧向变形对沉降的影响作用。试验结果表明，荷载作用下软土的瞬时沉降是非线性的，剪应力作用产生了不可恢复的侧向变形，侧向变形产生的附加沉降也是重要组成部分。软土的侧向变形在不排水条件下只有鼓胀变形，且持续发展；在排水条件下是鼓胀变形和收缩变形的迭加。在排水条件下软土的侧向变形发展过程和剪应力水平有关，在低剪应力水平下侧向变形对沉降的影响不显著，在高剪应力水平下则侧向变形对沉降的影响不能忽视，剪应力对沉降的影响贯穿于沉降全过程。

Abstract

The influence of lateral deformation of deep marine soft soil underlying embankment on its settlement through the triaxial and plane strain creep tests is studied. The result indicates that the relationship between the initial stress and strain is nonlinear

the shear stress produces unrecoverable lateral deformation which is an important component of the settlement. The lateral deformation expands all the time under undrained condition

while it not only expands but also shrinks under drained condition. There are corresponding relationships between shear stress level and the process of lateral deformation

when the shear stress level is low

the influence of lateral deformation on the settlement of roadbed is not so distinct

when it is high

the influence should not be neglected and it appears along the whole course of settlement.
