Road Slope Stability Analysis And Optimal Design Of Treatment Technology

With the fast development of domestic investment in capital construction, road construction and slope control encountered in geotechnical slope stability problems increase. Slope in the road construction and operation of the process, but the phenomenon of slope failure have occurred, and the slope once the instability, its often disastrous consequences. Therefore, the slope stability analysis for road and Treatment Research to develop an effective protective measures, a very important theoretical and engineering significance.In this paper, conducted extensive research on relevant topics, and based on extensive relevant literature information on the road slope stability analysis and computation theory in depth. Then, for the commonly used class of limit equilibrium slope stability analysis method is difficult to consider the slope of rock material within the non-linear stress-strain relationship of this defect, the use of elastic-plastic finite element method to simulate the process of slope failure, by analyzing the edge body of rock slope deformation and force the state about the use of lower yield strength of the material safety factor of slope reserve strength reduction finite element, and thus to explore and propose a set of comprehensive technology road slope.Finally the Treatment of optimization techniques such as anchoring engineering, grouting techniques, drainage measures design techniques to optimize the design steps. In this paper, the ink bar in Tibet highway K104+590～K105+700(BP15number) of the rock slope to detailed study, using the limit equilibrium method has been its natural state simulation of the stability coefficient of1.170, indicating that the side slope in the creep state; saturation stability factor of0.952(Bishop method), the slope is unstable state. Simulated the slope of the displacement, stress and strain of the situation, most likely derived from the slope to the top of the hill slope damage the internal pressure, and then cut out from the foot of the slope part of the failure mode. Finally, according to the engineering geological characteristics and slope stability evaluation results, the slope of the prevention and treatment recommendations.
