摘要
介绍了真空联合堆载预压法的边界效应,并通过真空联合堆载预压法加固机理、应力路径及强度增长,阐述了产生边界效应的原因,讨论了造成加固区边界效应的影响因素,最后提出了对加固区边界效应的防治措施。
The boundary effect of the method combined vacuum and surcharge preloading is introduced. Through introduction of the reinforce- ment mechanism, stress path and strength increase of the method combined vacuum and surcharge preloading causes of boundary effect are analyzed, at the same time factors influencing the boundary effect of reinforced area are discussed. In the end corresponding prevention measures are proposed.
