盛土斜面の安定性に関する検討

Abstract

Civil engineers who are engaged in construction of such facilities as railways, highways, housing lot, levees and embankment dams often encounter slope failures during and after construction. Characteristics of these slope failures and mechanical explanations on them are discussed in this paper together with some useful counter measures to be adopted in both design and construction stages. Special attentions were paid in the first half on the evaluation of the excess pore water pressures built up during construction and the seepage water pressures grown after construction due to rainfall and so forth, which for the most part contribute to slope failures of earth embankments. In the latter half, several useful methods of counter measures against slope failures are proposed in such ways as protection of sloping surface, setting drainnage facilities and reinforcement of embankment body.
