Observational method in the design of high cutting slope around bridge

摘要

The authors mainly discussed the idea and flow process of the observational method in thedesign of high cutting slope. This method is based on our accumulating knowledge on slope failure includingsite investigations,site tests,and site monitoring data. It was emphasized that measures for slope protectionshould implemented in stage,in groups,and in time to make the design scheme more economics and reasonable.As an example in the application of the observational method in design,a project of high cutting slope around abridge was presented. This project is located in the Tongling side of Taipinghu Bridge of Tongling--Huangshanexpressway in China. The result indicates that the safety and economical viability of the high slope is guaranteedfor its entire expected engineering lifetime.
