Description

Anchor cable frame combined retaining wall reinforcing method and structure for unstable slope
Technical Field
The invention belongs to the technical field of slope reinforcement, and particularly relates to a method and a structure for reinforcing an anchor cable frame combined retaining wall for an unstable slope.
Background
In engineering construction, slope instability damage is one of the more common engineering problems, such as sliding damage of peripheral slopes easily caused during bridge, highway and house construction. When the slope problem is treated, the instability of the slope after engineering reinforcement still occurs due to the extremely complex structure and the diversity of characteristics of rock-soil mass. Data show that the economic loss of China caused by geological disasters such as landslide and the like is as high as 80-200 billion yuan each year. Therefore, the design and construction process in the early stage of the engineering should be careful, and serious engineering accidents can be caused by slight carelessness, which can bring great harm to the property and the safety of people. At present, due to the fact that human beings have not enough knowledge about the damage condition of some side slopes, the excessively conservative side slope design support causes excessively high economic cost of side slope maintenance engineering, unnecessary waste is caused, unstable accidents with different scales often occur on the side slopes, new problems often occur on the road side slopes along with the progress of the construction process, particularly, the soft rock and loose body type side slopes are easy to be disturbed by engineering to cause landslide, and manpower, material resources and cost are required to be continuously input for renovation, so that constructors are quite passive in the face of the landslide problem, and meanwhile, a lot of hidden dangers are buried for operation management in the later period of the road.
Although the slope reinforcement method is numerous, with the advance of modernization process, the scale of engineering construction is continuously enlarged, and the height of the slope is increased, so that the requirement on the slope reinforcement technology is higher and higher. The slope reinforcement in engineering includes four slope reinforcement measures, namely a prestressed anchor cable method, a grouting method, an anti-slide pile and a retaining wall. The retaining wall technology is a mature technology for engineering application, but a single retaining wall technology only depends on self structural self weight and shape characteristics to resist the side slope lateral soil pressure, although the anchor cable and anchor rod are arranged in the retaining wall to improve the capability of resisting the side slope lateral soil pressure, the anchor cable and anchor rod and the retaining wall structure cannot form a combined action, the overall rigidity is limited by the design and construction process level of the wall body, and the side slope still has the problems of insufficient stability and structural strength and the like.
