摘要
简要回顾了非饱和土力学的研究历史及研究意义。结合南水北调中线工程中的膨胀土问题,探讨了非饱和土理论在渠道工程设计中的应用前景,重点论述了非饱和土抗剪强度理论及其简化计算方法,并从膨胀土的破坏机理、变形特点和强度特征出发,探讨了膨胀土渠坡工程处理措施和处理原则,为南水北调中线工程膨胀土渠段的设计和施工开拓了新的思路。
The research status and significance of the unsaturated soil mechanics at home and abroad are reviewed. For the problem of expansive soil at the Middle Route Project of South-to-North N Water Transfer, this paper covers an analysis on stability method of expansive soils slope, determination of expansive soils strength, rational design of canal slope ratio and support.
