Slope Stability Analysis And Calculation Program Design

The problem of slope stability is always an important research subject in the civil engineering, and it relates to railway and highway engineering, hydrological and hydroelectric engineering, construction engineering, bridge engineering, tunnel engineering, waste residue and garbage management engineering, etc. With the fast development of domestic economy, the construction is on the increase every day. The problem of slope failure will be more and more serious. It may result in the landslide of the slope, and even destroy the whole foundation or cause to lose people's lives and their property. So the problem of slope stability analysis is very important.This paper followed the research route as reading compation-field investigation-establishment of calculation model-design of program-analysis of case .It classed the motheds of slope stability analysis and founded the model of homogeneous earth slope on the base of limit equilibrium theory. It gives an advanced search method for finding the critical circular slilp surface using Monte Carlo technique in this paper. It can search for the slip surface of slope in all calculational field by optimized step fastly and exactly at random. It adopts the predigest Bishop method to calculate the least safety factor of slope. It gets the exact result for avoiding treat with the question simply in other methods of slope stability analysis. Visual Basic 6.0 is used in the design of program, It realizes the visal of locate the critical circular slipe surface and dynamic show of calculate the least safety factor of slope through design of dynamic coordinates. The calculating program has many advantages, such as interface amity, operate simple, fucation reliable, result perspicuity, etc.Two practical projects were selected as the calculation cases, and analysis of the calculation results were made. The results showed that the calculating theory and the calculating program are reliable and suitable.
