【摘要】 溪洛渡水电站工程规模大、技术难度高,其挡水建筑物为双曲拱坝,坝高278m,总装机容量12600MW。坝址区河床部位及两岸谷坡的基岩主要由二叠系上统峨眉山玄武岩组成。玄武岩共分14个岩流层,在各大层间及层内发育了一系列层间错动带和层内错动带,形成了控制坝区各类工程地质问题产生的基本条件。本文就层间层内错动带变形稳定问题;层间层内错动带抗滑稳定问题;层间层内错动带渗透变形问题;陡倾角侧裂面抗滑稳定问题;以及结构面倾角对岩体力学性质的影响等问题开展的试验研究做出了较为详细的介绍。。更多还原

【Abstract】 The technique difficulty is high and project scale is pulled through greatly in the XILUODUhydropower station. That such wards off the water building act as twin arch embankments, Embankment tall 278m,Installed capacity 12600MW invariably. Chiefly consists of the Permian System EMEI mountain basalt in bedrockof district riverbed and two coasts slope of embankment site place. Basalt in all branch 14 crag runs tier, The faultstir girdle of rock stratum between fault stir girdle and rock stratum inside of a series between every great tieramong and tier inner place, Different type of basic condition that the project geology problem was come into beingin the control embankment district take shape. The dissertation adjust problem of deformation steady of fault stirgirdle of rock stratum between and rock stratum inside; The problem of combat slip of fault stir girdle of rockstratum between and rock stratum inside; The problem of seep deformation fault stir girdle of rock stratumbetween and rock stratum inside; The problem of combat slip of precipitous dip side crack surface; Makeintroduction of relatively detail launched research and test to the problem of effect of composition surface dipadjust rock mass mechanics nature.更多还原
