微型桩作为近年来兴起的新型支挡结构,因其具有独特的优势,在边坡整治和加固工程中得到广泛应用。文中在总结前人研究工作的基础上,对微型桩的3种常用设计计算方法及基于物理模拟和数值模拟的模拟试验研究方法进行总结及探讨,认为现有对于微型桩加固边坡设计计算方法通常是基于某种假定或限定条件,而数值模拟大都是基于理想化模型开展研究,但实际工况要相对复杂,因而适用条件以及加强理论与试验相结合尤为重要。此外,国内外对微型桩的布置方案及不同布置方案下受力特点的研究较少,因此该研究有待于进一步完善和发展。
As a new type of support structure that has emerged in recent years, micro-piles have been widely used in slope improvement and reinforcement because of their unique advantages. Based on the summarization of previous research work, this paper summarizes and discusses three common design and calculation methods for micro-piles and simulation test research methods based on physical simulation and numerical simulation. It is considered that the existing design methods for slope reinforcement Usually based on a certain assumption or qualification, and the numerical simulation is mostly based on the idealized model to carry out research, but the actual conditions to be relatively complex, so the application of conditions and to strengthen the combination of theory and experiment is particularly important. In addition, there are few researches on the layout of micro-piles and the mechanical characteristics under different layouts at home and abroad, so the research needs to be further perfected and developed.
