Disadvantages of cementsoil retaining wall: the first is the relatively large displacement, especially in the pit length is large, this may be done between the piers, arches and other measures to limit the displacement is too large, followed by thick, only used in position and the surrounding environment allowing the red line, and in the construction of cementsoil mixing piles to avoid affecting the surrounding environment. soilnail wall is a type of slope stability of soil nailing wall support, its role and passive retaining walls are different, it is voluntarily fixing effect, increase the stability of slopes, excavation of Foundation pit slope stability. Soilnail wall is better soil areas, applied along the northern part of North China and East China, also in southern China, and some has been used to hang 10m deep Foundation pit, stability, construction is simple and short, good, good economy, better soil areas should actively promote. Used soil nail wall of General requirements, ① soil nail wall can applies Yu plastic, not plastic or hard of viscous soil。 II in has groundwater of soil in the, soil nail support nursing should in full drop drainage of premise Xia used。 ③ soil nail wall easy caused soil body displacement, used soil nail wall support nursing should carefully consider, wall body deformation on around environment of effect. row of piles during excavation, not sloping or due to the limited space and cannot stir pile, depth at around 6 to 10m when you can row pile
