Abstract

The invention provides a prevention method for filling roadbed slope stabilization. The prevention method comprises the steps of determining whether a sloping space exists in a filling roadbed or notaccording to requirements on a terrain, an external environment and a part of the filling roadbed; if the sloping space exists in the filling roadbed, planting grass on a slope of the filling roadbedafter filling the filling roadbed layer by layer; and if the sloping space does not exist in the filling roadbed, filling the roadbed layer by layer, and meanwhile, fixing a tie bar, broken stones anda retaining wall panel layer by layer to form a reinforced retaining wall slope. According to the prevention method provided by the invention, different prevention methods are adopted according to the requirements on the terrain, the surrounding environment and the part of the filling roadbed, so that the applicability of filling roadbed slope treatment is improved, the scouring resistance of thefilling roadbed slope is improved, the prevention method is particularly suitable for preventing the hazard of first-class soil filling roadbed sliding, and the stability inside and outside a road embankment is improved.

Description

technical field [0001] The invention relates to the technical field of civil construction, in particular to a method for preventing and controlling the stability of a filled embankment slope. Background technique [0002] At present, slope is an important part of highway engineering, and the overall effect of slope protection directly affects the overall stability of road subgrade. Common methods of cutting slope protection include engineering protection, vegetation protection, and the combination of the two protection methods. [0003] The Sri Lanka expressway is a two-way lane, and its roadbed is filled with locally treated low-chlorine sea sand, and the roadbed side slope is constructed at the same time as the rolling construction. Sea sand has the characteristics of easy compaction, good water permeability, high water stability, and large internal friction angle. It can be used as roadbed filler, but when it is used as the main material of a slope, it is easy to be scou...
