A Engineering Feasibility Study Of Rock Bank Slope At Mashuihe River Bridge Site

Rock mass engineering geological problem of bridge site in gorge slope reflect the discrepancy between human engineering activity and engineering geological conditions. Presently, this problem has been studied little, especially comparing to mine slope and water-power engineering slope. Meanwhile, its own typical characteristics compared with latter two type slopes. High-steep slope rock mass, as a kind of complex material indwelling in special geological environment, behaves as discontinuity, in-homogeneity, aeolotropism, otherness of living conditions, and the various distortion and failure form of the rock mass under the function of engineering load. Thus, the rationality of stability assessment and the feasibility of the project measures comes to be complicated and im-exercisable. But, In response to the need of construction, these problems need be solved such as how to choose the optimal bridge type and how to arrange the abutments, which impact the bridge site slope stability, and connect with bridge safety and the cost.Bridge site slope of Mashuihe River is acted as a typical case in thesis. Based on the qualitative analysis of rudimental engineering geological conditions of the slope, rock mass quality is assessed, and slope deformation and failure models are generalized, in addition, finite element analysis method is used to examine and certify the models. Then, stress distributing and displacement changeing characteristic in slope are researched under the conditions of bridge load and reservoir impound process, the engineering feasibility of rock bank slope is studied from the angle of interaction between rock slope and bridge project. Finally, a systematic method is summarized which used to assess feasibility of high-steep rock bank slope, the whole work is focus on using rock mass and directing rock slope engineering reasonable. So, it's a glamorous topic not only for theory development but project practice application.Therefore, the research methods adopt in this thesis is as follows: firstly, according to related data which are achieved by practical research in the field and consulting reference, rock character, geological structure, hydrogeology condition and human engineering actions which are located in study zone are analyzed, then rock mechanics environment conditions including rock mass structure, rock mechanical property and initial stress filed in study zone are studied with...
