Slope Stability Analysis Of The Load Coefficient Method

Soil slope stability analysis is an important research topic today. Actual engineering in now, how the stability of the slope is not only related to the economic, but also related more danger to personal safety. The slope stability analysis is divided into two parts, the one is to solve the safety factor, the second is to determine the critical slip surface.At the moment, the most widely used method to solve the safety factor is limiting equilibrium. According to the different inter-strip force is assumed, then there have different derivative methods. Solving safety factor are generally indicators of soil material strength reduction, making the safety factor equation solving implicit equation calculation process requires iterative, not good convergence. Vertical slice method basis by the slope may slide a volume force is applied to the force of law and bar bottom reasonable assumptions, then draw a load factor through rigorous derivation process, display solutions. A similar approach has been the safety factor display solution. In this way, the assumed theoretical basis for a more reliable fully traditional solving safety factor, but also compensate for the calculation process is lengthy and bad convergence defects. Secondly, the-theoretical relationship between research solutions and safety factor solution-found by loading coefficient, the load factor display solution with the safety factor solution into a reciprocal relationship, the two are inverse operations. This makes solving the safety factor is more simple, and checking each other, to make the results more accurate. Again, by loading coefficient method to establish the the slice method unified equation strictly meet the limit equilibrium conditions, a new method is used strictly meet the limit equilibrium conditions derived from the limit equilibrium method, given a new content. Finally, a numerical example checking the correctness of the conclusions, the feasibility, the new method can be widely applied in practical engineering to provide reliable data.
