Stability Analysis Of Rock Slope Based On Ant Colony Algorithm

Landslide has brought about great losses to the economic and societal development worldwide. Each year it causes a loss up to billions of dollars in the whole world. In china, 70% of the area is covered by mountains where landslide hazard happens frequently and densely. China is among those countries stricken most by this hazard. In recent years, with the increasing of the quantity and the scale of engineering construction, the disasters of rock slope failure take place frequently. The relevant loss also increases year by year. Therefore, it is more and more important to research the stabilization of rock slope.The important problem in slope stability analysis is search of critical slip surface, which has direct relation with credibility of analysis result. Presently, Mostly search methods of critical slip surface are mathematic programming and intelligent search method.There are lots of joints in rock slope, safety of rock slope is controlled by joints, but there are a few of joints whose direction is vertical, a majority of joints' direction is not vertical, so the Sarma is adopted to be the safety analysis method of rock slope. Because of that, developed safety estimate system on rock slope in this paper. This paper researches the property of discontinuity and simulates it. Based on outdoor investigation, this paper is about analyzing discontinuity's geometric property, studying on net work with computer, with real project, getting geometric modal .It can analyze safety of rock slope. We didn't suppose several critical slip surfaces before confirming the safety factor, using the program which is edited by itself to search the critical slip surface- The safety analysis system searches the critical slip surface based on the least shearing strength and adaptive ant colony algorithm. Before searching the critical slip surface, using Joint Network Simulated program to recurrence joint distribute in the slope and point joints. After the critical slip surface confirmed, the system separates inclining the slope automatically and computes the slope safety factor.We used the safety estimate system on rock slope to analyze the the slope of anti-fire road of mount xiang northen chimb. The result is coincident to the real condition of the slope, so the safety estimate compositive system on rock slope is relatively viable.
