Stability Analysis And Simulation On Prestressed Anchor Cable Frame Beam Reinforcement Effect Of The Slope In The Huanglingno.1 Mining

With the rapid development of China's infrastructure construction,highway,housing construction and mineral development in the construction of artificial slope is increasing,the resulting slope disasters are also increasing,therefore,how to more efficient and reasonable slope to reinforce governance has the important meaning of theory and practice.Prestressed anchor cable frame beam as a new slope reinforcement technology,has been promoted by a large number of applications in the engineering practice,however,ahead of the practical application of theoretical research,there are still some problems in the production practice,therefore the theoretical study of the technique is of great significance.Based on the huangling mining no.4 well wind number one slope as the research object,USES the traditional analysis method and numerical simulation,the two methods for slope stability evaluation,through fuzzy comprehensive evaluation concluded that the optimal reinforcement scheme,and its reinforcement effect in the finite element software simulation prediction,basically have the following conclusion:(1)using the limit equilibrium method and finite element strength subtraction,huangling mining no.4 number one wind Wells are calculated separately,and the slope stability,it is concluded that the following evaluation:in natural condition of slope is in unstable condition,working condition of heavy rains in a state of instability,the slope landslide reinforcement.(2)to compare the advantages and disadvantages of the current slope reinforcement measures and the suitable conditions,using fuzzy multi-objective fuzzy decision optimization of huangling no.1 mine wind Wells slope reinforcement is the most reasonable solution 4:prestressed anchor cable frame beam reinforcement measures.(3)in the finite element software GTS NX modeling scheme of reinforcement design and simulation of prestressed anchor cable frame beam slope after reinforcement stress are obtained.Cloud strain and the plastic zone distribution,calculated the natural conditions and heavy rain conditions huangling mining no.4 well wind number one slope stability coefficient is 1.382,1.165 respectively,reach the grade of slope safety factor design,verify the reinforcement scheme is reasonable.
