The Synthetical Evaluation Research On Slope Treatment Program

Nowadays,the engineers are facing more and more slope treatment engineering in the fast infrastructure development of the country,the slope treatment technology is mature,however,there doesn't have a complete set of evaluation index to evaluate a optimal slope treatment scheme nor measure the pros and cons of a slope engineering.In the practical engineering,especially those small scale projects,there exist many subjective designs and construction which may cause big waste of manpower,material resources and financial resources.The paper planed to make optimization of an designation and construction scheme for the slope treatment,which made a building slope in Chongqing Nanshan as the research object,studied the influence factor of slope treatment engineering,proposed a synthetical evaluation method to assess slope treatment result.In the paper,the writer developed a series of researches,The main contents are as follows:?The paper mainly summarized the knowledge and methods of the Fuzzy Theory,the concept of Fuzzy Set,Membership Function,Fuzzy Logical Operation,the Principle and concept of Fuzzy Evaluation and Synthetical Evaluation Model.The paper had state the step of building the synthetical evaluation model in detail.Meanwhile,paper discussed the way to certain weighted value,which based in fuzzy analytical hierarchy process.These work provided a theoretical basis for the research in the slope engineering treatment results.? The paper combined with a large number of engineering,searched relative information,summarized the influence factor for slope engineering in hierarchical and classified.The paper concluded four main factors including security factor,technological factor,economical factor and environmental factor for the slope treatment engineering.Besides that,there also have several sub-factors among these main factors.After that,paper got the influence factors index for slope treatment engineering to guide the engineering practical application.?The paper used limit equilibrium method and FLAC3D numerical simulation method to analysis the stability of slope excavation and the supporting effect for an project case,from which the author got the pre-excavation,post-excavation and after support effects for the entire stability of slope.? The paper established a set of synthetical evaluation model fitted for slope treatment engineering assessment,and then,made one building slope in Chongqing Nanshan as an example to process theory analysis and comprehensive evaluation for the slope treatment engineering.From the example,the paper got an feasible method for optimize the slope engineering proposal.
