【摘要】 土钉支护是近年来在国外发展起来的一种用于土体开挖和边坡稳定的、基于土体自承的新型挡土结构，我国自九十年代引进以来己得到广泛的应用，但其作用机理和工作性能尚有许多不甚明了之处，存在理论滞后于应用现象。 本文在参阅了大量的文献资料的基础上对土钉支护的支护机理、工作性能和稳定性分析计算做了较全面的论述，并结合工程实际，对土钉支护的工作性能做了一些分析研究，对特定土层中的土钉支护边坡的破坏做了分析，并对土钉支护在软土地基中应用和超前锚杆的工作机理做了初步探讨。 实践证明，土钉支护是一种经济、便捷、实用、能适用于许多不同地质条件下的支护结构，通过采取一定的措施可应用于浙江的软土地层，具有较高的推广价值。更多还原

【Abstract】 Soil nailing supporting is a new technology developed from abroad in recent years,to be used in excavation of soil.slope stability and the new retaining structure base on soil-bearing. We had already wide used it in ninties after the techique introduced.At present,we don’t know thoroughly in mechanism and performance ,which theory are behind the application.In this paper,based on a lot of documents and data.mechanism.performance.analysis of stability of soil nailing supporting are discussed and analyzed in detailcombining with projectanalyzed and studied the perfornmance of soil nailing,especially the damage of soil nailing supporting to specific soil layer, the application of the soil nailing to soft soil foundation and mechanism of forepoiling bolts are also expounded.Practice has proved that soil nailing supporting is a kind of economical , convenient, practical technique suitable for different geologic conditions. After taking measures, it can apply to the soft soil in ZheJiang and can wide spread .更多还原
