Based On The Theory Of Reliability Optimization System Compare Of The Landslide Treatment

Landslide is one of the natural disasters that human have to face with. With the increasingof human activities, landslide disaster to human influence is more and more bigger, the rangeis more and more wider, the landslide engineering experience gained by the governance thereare many, but overall is still in the process of exploration and summary, moment also can’tstop. In addition to the classic mechanics model is adopted to landslide stability is analyzed,the dissatisfaction with the status quo at home and abroad scholars, start based on the theoryof landslide disaster management of the other. This article is based on the traditional meaningof the mechanics analysis, introduces the concept of structure system reliability of landslide.A concept of structural system reliability is the structure as a whole, at the same time considerthe variation of load and strength, can also give full consideration to the size of the structureof uncertainty; Also comprehensive study component during the future work of randomness,the structure parameters of simulation into random variables, so as to make the structure’sresponse (stress, displacement, etc.) is a random.While thumbing through some of the authors of this article after a certain number ofChinese and foreign literature, writing this thesis has the following a few key points. First ofall, by introducing the concept of structural reliability and system reliability concepts, thenintroduces the principle and structure of the system structural reliability optimization designbased on reliability theory, and considers the formation mechanism of the landslide and itsstability analysis method, using the basic concept of system reliability theory, the basicalgorithm and basic flow, and ultimately to specific calculation method (i.e., the probabilityestimation network, referred to as PNET method), the landslide treatment engineering of aconcrete example of tentative optimization design to the retaining wall design. Through andafter comparing with the results calculated by traditional design, the calculation results showthat the landslide retaining wall based on the theory of the system reliability optimizationdesign is feasible, and has good engineering significance.
