Abstract: In order to achieve better effect of siphon drainage technology in slope application in a loess area, the design of siphon drainage hole spacing considering loess anisotropy was carried out. Based on Neuman theory, according to the different degree of soil permeability coefficient, the anisotropic seepage law of loess was considered, the concept of interception ratio was introduced, and the relationship between depth drop and influence radius was combined. An analytical solution of siphon drainage spacing suitable for anisotropic soils was derived. The results show that the spacing of siphon drainage holes is not only related to permeability coefficient and depth drop, but also to the ratio of vertical permeability coefficient to horizontal permeability coefficient. In the actual case project in Heifangtai loess area, 0.4 m is the optimal distance between the siphon drainage holes. The numerical simulation and analytical calculation show that the interception ratio (49.7%) meets the practical requirements when the spacing of single row of drainage holes is 0.4 m.

Key words: siphon drainage, hole spacing, radius of influence, anisotropy, slope
