考慮節(jié)理影響的某巖質(zhì)邊坡穩(wěn)定性分析
[Abstract]:With the rapid development of mining, transportation, water conservancy and construction, the number of rock slope projects such as open-pit slope, waste rock field, tailings dam and highway and railway cutting slope has increased sharply and the slope is unstable. Landslide and other disasters occur from time to time, and slope stability has been paid more and more attention. Therefore, the analysis and calculation of slope stability and the study of engineering measures still have important theoretical and engineering significance. In this paper, taking a rock slope as an example and taking a certain rock slope as an example, according to the actual situation, the factors affecting the stability of the slope and the possible conditions of the project are analyzed, and the most unfavorable working conditions are found out, and the method of plane projection is adopted. The Bisop method and the Mogenstern-Price method are used to analyze and calculate the slope stability considering and disregarding the influence of rock joints, respectively. The results show that these methods are effective methods for judging the stability of jointed rock slopes. It can reflect the sensitivity of rock structure to the stability of rock slope and verify the adverse effect of joints on slope stability. Mogenstern-Price method can also consider the situation of combined sliding surface. On the basis of the above analysis and calculation, different schemes of engineering treatment and protection measures for unstable slope treatment are put forward, which can be used for engineering design and construction. The results of this paper can be used for reference to similar projects.
