摘要: 通过离心模型试验和三轴试验,研究了土固结程度与抗剪强度的关系。表明:抗剪强度随着固结度的增加基本呈线性关系,与以往经验相符;c,φ值随固结度U的增加而增加,但增加的幅度逐渐减小,且不呈线性关系,可以用双曲线关系模拟。在此研究基础上,提出了一种在土体固结过程中根据实测沉降量估算土体固结度和强度增长的方法。

Abstract: By using the methods of deformation rate,statespecified criterion and engineering experience,the different controlling indexes are given for different monitoring instrunments.Through three links of design,construction and monitoring,a closed cycle system is set up for the monitoring of stability of high slope of Three Gorges Prject permanent lock.
