Mechanism Of Soil Nailing Supporting And Application Of Soft Soil Foundation Supporting

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 .
