Dynamic Design And Engineering Practice On Treatment Of Huge And Complecated Mass Side Slope Based On Information Feedback System

This article details the treatment plan, practice feedback and results analysis study on dynamic design and engineering practice. It is based on the practical example of creep treatment for Yinshuigou mass slope at Xiaowan,project, with the objects to assure the stage of flood protection , closure and permanent stability. The method model combined theory and practice has been adopted on this study to mainly solve the engineering practical problems. Schemes of solution would be analyzed in suitability and rationalization through the monitoring information results.The study aimed to find a way solving the stability problems of huge and complicated mass slope through the analysis of genetic and mechanism, study of safety standard control and zoning parameters, planning of creep treatment and analysis of results. The dynamic design and engineering practice on treatment of Yinshuigou mass slope is based on the information feedback system for the slope. It has determined the suitable geology mechanical parameters and simulated margin conditions based on the results of past tests and inversed analysis, and zoned suitably for different collapse mechanism. Step and zoning safety control standards have been decided based on the characteristics , breakdown mechanisms and the buildings nearby of slope parts. The assurance system mainly adopted for monitoring information feedback and construction treatment control is effective. Ordered and rationalized information feedback and dynamic treatment procedures have been choosen, so suitable treatments and planning are also made and done by step and zoning.If the method of dynamic treatment by information feedback have been adopted on the kind of slopes which belongs soils and being huge and complicated masses, the suitability and rationalization of treatments and the scientific and reasonability of treatment done procedure would be improved. That would solve the uncoordination within the construction progress on excavation and engineering treatment of the slopes, and would be useful for reaching the object of low treatment works and high safety steady on slopes. But it is not suitable for the rock shopes because of the brittle and sudden failures, and it is not necessary for the kind of slopes which belongs soils and being small and middle scale because the coordination within the construction progress on slope engineering treatment is not sharply and limited by the slope scales. After the dynamic treatment by information feedback, steady state of Yinshuigou mass slope has assurced the objects on flood protection and river closure in 2004. Nowadays all treatments for the slope have been finished and the slope has been examined over 2 rainy seasons. Yinshuigou mass slop is under the steady state supported by so much monitoring results. This design and practice successfully gives a solution to treat the huge and complicated mass slope, gains the social benefits and economic benefits at the same time,and it is useful and important in treatment reference on the kind of slopes which belongs huge soil masses and creeps slowly.
