微型桩加固边坡计算理论及试验研究综述

Reviews of Theoretical and Experimental Researches on Applications of Micro-pile in Slope Reinforcement

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。

Micro-pile as the rise of new retaining structure in recent years, because of its unique advantages, is widely used in the renovation and reinforcement of slope engineering, in this paper, on the basis of summarizing the predecessors＇ research work, three calculation methods for design of micro-pile and simulation test based on physical simulation and numerical simulation research method summarized and discussed, thought the existing for micro pile reinforcement slope design calculation method is usually based on some assumptions or limit conditions, and the numerical simulation studies are mostly based on the idealized model, but actual condition is relatively complicated, thus applicable condition and strengthen the combination of theory and experiment is especially important. In addition, both at home and abroad of micro-pile layout and the mechanical characteristics under different layout plan of study is few, so the research needs to be improved and developed further.
